Do not use them if you want to keep your revenue

Absolutely disgusting service. I've bee running a Limited company for over a year and fully registered with ample finances records. I recently decided to to try SumUp for my website due to the low transaction fees. After many sales without issue, i receive an email requesting 2 answers to 2 simple questions. Nothing major and easily answerable. 3 days after submitting, i was told my account would be terminated, and i cannot appeal. All refunds with be kept for 2 MONTHS or i can refund ...

I use my SumUp for craft fairs as it’s easier for people to pay rather than using cash. Also it never lets me down with bad internet connection. So simple to use and a definite must for even technophobes like me.

Solo device blocked. Just a few days out of warranty.

Turned on my Solo ready for the Craft Fair season. It is blocked and directed me to request a free replacement. When I did they said it is out of warranty. Never was happy with this product or company. It was intermittent in working the few times I used it. I had only got it as backup for a Zettle card reader, which works brilliantly. I bought the Solo (13902200100177696) on 26/5/2022. It cost £79.20. I was attracted by the integral SIM which was supposed to work when wifi was not ...

No support whatsoever

The actual card reader works fine but we needed to add some extra hardware to our setup. Spoke to 5 different people all with a different answer (none of which work) asked online support for assistance who finally said they would ask tec support to get back to us and it's been 6 weeks with no response. Useless

I purchased less than a year ago the device for cards, used it once and kept it in a drawer safely. Turn it on and the device is blocked and asked to contact customer support they will send a replacement. Provided them with a SN and the warranty seems to only after 6 months of purchase. They blocked the device and ask me to buy a new one, they say it has been drop or exposed to higher temperatures which none of the two are true as it’s been in its box, and with energy prices extreme ...
