Possible the worst company ever

Absolute residual of a company. Complete disregard for customers, zero customer service and lies upon lies. Hold huge sums of clients money. Numerous emails telling me dates money would be in account and still no money. Unable to pay my bills, fees kids etc due to these thieving con merchants. Formal complaint made and reported to ombudsman. I cannot stress enough how vital it is that you do not use this company if you value your business.

Had a client transfer money to my account for purchasing a business service, it’s been over two weeks and I still haven’t had any access to my money as they are investigating the payment, have sent proof of payment details but still no reply. Poor customer service. Stay away from this company!!

Sumup support is not fit for purpose

Our organisation has changed its signatory but Sumup appears to be not able to do so. Instead they closed the account and demanded the return of our card reader. No explanations either. Every time I email support to try to get to the bottom of this I receive a standard reply, failing to address any of the issues. Sumup support is not fit for purpose. Having now read their reply to this review, I have to say they are not stating the truth - they say we "were invited to open a new profile ...

We run a pub and card reader goes off for hours costing us a fortune. We ring customer service and after 40 minutes the best they can offer is, either call back when it happens again !! Yeah right a Sunday evening at 6pm with a bar full of people trying to get served. Or switch it off and on again. Absolutely useless avoid avoid avoid. Get a proper company or go through your bank. This is no frills diy outfit that will leave you out of pocket and not care less
