Avoid Sumup as app and website don't work

Having used a paypal card reader for years I was attracted by the lower rates offered by sumup, ordered a machine which arrived quickly. That's when the problems started. It is basically a useless lump of plastic. Both the website and app no longer work so it is now impossible to verify yourself in order to take payments. Their customer service is also woeful, the assistant admitted there was a 'technical' problem, but as of 31/8/22 they had no idea how to rectify the issues. Spent £40 for ...

Currently waiting on payout of two transactions since Sunday ? Spoke with 4 different agents - told 4 different reasons - now have been told it will be Friday before money is in my account ???? 6 full days ???? Very poor. Not at all a happy customer.

Shocking communication and customer service. Beware!

SHOCKING

SHOCKING. Sumup holding on to funds required to run my business for absolutely no reason. I supplied the required invoice info and description of payments the same morning they were requested, then heard nothing back with no updates. Repeated calls to service team proved next to useless. Still holding 7k after nearly a week, even after being told I needed the payment to cover wages. They're holding on to our money while it builds interest in a nice fat account. Where is my money Sumup??

Drastic action that needs to be taken

Twice recently there has been a major outage at weekends. The most recent of which was on Saturday of the Bank Holiday weekend. I emailed SumUp with image grabs from the outage and I was offered a derisory £25 compensation each time from the 'support team' I included the MD in the email and had no response from him on either occasion. In addition to this the card machine keeps becoming 'inactive' and regularly has trouble connecting (it's also the 3rd one we've had in the last 18 ...

Awful experience - AVOID

Awful experience with this shambles of a so called company. Incorrect bank details added to my account and then only a stand being sent from my order and no reader. Called them and the agent couldn’t advise when my full order would be sent. Avoid this company!

Easy when you know how!

Apparently I had my NFC switched on in my phone settings! Kind Sean talked me through what I needed to do to make my card reader accept payments properly, and hey presto all is well for my next craft fair! Isn't technology great!

Absolutely pathetic hardware, here’s why.

Absolutely pathetic hardware. Sumup have asked for more details so I will give more details; taking the sumup 3G out of the box I could tell within minutes that the battery was no good, took 2 hours to change from 0% battery to 1% battery. When it hit 100% battery I turned it off and left it overnight, the next morning it was at 69% battery. Lots of people saying the battery is useless not fit for purpose in my opinion. When the machine is in standby mode or off it keeps making a strange ...
