Debit Card Reversal

Your question is slotted to Groupon, so although your Groupon issue is not clear, we can't resolve it here at Help Owl in any case as we're an independent help site with no access to your account. If it is indeed a Groupon issue:

Groupon in the U.S. is not currently offering phone access. You can however write the company at [email protected]. In the U.K. you can write directly to [email protected] or (probably) phone +44(0)203 510 0410. If worse comes to worst (I don't expect it will be necessary), you can complain to the Illinois Attorney General, at 618-529-6400.

If it's an issue with your bank, it must be resolved with the bank. If you need contact information, a good source is https://www.contacthelp.com/.
