Different Mistakes, Different Fixes — Find Yours Below

This page doesn't replace the detailed guides on each topic — it's the fast triage step for the moment you realise something's wrong and need to know what's actually possible, not the full explanation. Find your situation below and go straight to the right action.

Find Your Situation

What went wrongWhat's actually possible
Wrong delivery address enteredCargosender's terms state address changes after label creation are not accommodated, and delivery to a different address isn't guaranteed. Contact support immediately in writing regardless — the earlier you flag it, the more options may exist before the label is actually created. See the address formatting guide.
Wrong weight or dimensions enteredThis is likely to surface as an additional charge when the courier measures the real parcel, not something to fix retroactively. See the guide on unexpected charges after booking for what to expect and how to dispute it if your own figures were actually accurate.
Want to cancel the order entirelyCargosender's terms require cancellations to be made in writing. If the shipment has already been handed to the logistics provider, you remain responsible for costs incurred.
Declared the wrong valueTreat it as final once booked — the terms don't describe a process for changing it afterward. Contact support in writing if the error is significant, but don't assume it can be corrected automatically. See the declared value guide.
Realized the item is actually prohibited or restrictedContact Cargosender support in writing immediately, before the shipment is collected if at all possible — see the shipping restrictions guide to confirm the item's actual status.

What All of These Have in Common

⚠️

Cargosender's terms require cancellations, modifications and complaints to go through written communication channels to be treated as valid — a phone call or chat message alone may not count.

⚠️

Acting immediately, before collection happens, generally preserves more options than waiting to see what happens.

⚠️

None of these mistakes are fixed by adding a note to the delivery instructions field — that field passes a message to the driver about an address already booked to, it doesn't change any of the underlying order details.

What to Include When You Write to Support

Since the terms require this in writing anyway, a complete first message is what actually saves time — support has to ask for anything missing before they can act, which costs you the immediacy that matters most here.

Your order number or tracking number, not just your name or email.
Exactly what's wrong, stated plainly — the specific field (address, weight, value, item description) and what it should be instead.
Whether the shipment has already been collected — this changes what's actually still possible, per the situations above.
What outcome you're asking for — a correction, a cancellation, or just confirmation of what will happen next — rather than only describing the problem.
A phone number where you can be reached quickly, in case support needs to clarify something before the collection window closes.

Frequently Asked Questions

I entered the wrong address — can I still fix it?

Not reliably. Cargosender's terms state address changes after label creation aren't accommodated. Contact support in writing immediately regardless, since acting before the label is created gives the best chance of a fix.

Can I cancel my order after booking?

Yes, but it must be done in writing per Cargosender's terms. If the shipment has already been handed to the logistics provider, you're responsible for costs already incurred.

What if I realize my parcel is actually a prohibited item?

Contact support in writing immediately, ideally before collection. Don't wait to see if it gets flagged during transit — see the shipping restrictions guide to confirm the item's status.
