Worst customer service ever experienced

Bought a small unregistered business 2 years ago which included a Yoco reader. Changed ownership at the time and only recently decided to use it for another small business I started. Changed the business name on the profile and then saw that it was under my name but the previous owners ID and bank details are still on the profile. Tried to change the bank account details and uploaded my statements. Takes 1 day they say, mmmm I waited 4. No response. Tried for 3 days straight to get some help only to be told they can't change the ID. How the hell did Yoco change the name but can't change the ID? It is a useless situation. Talking to Bots, Live chat to consultants that only have standard responses. Pulling my teeth with chopsticks without anaesthetic would have been more pleasurable. I was told to reregister and create a new profile but the email address I use already exists on their system. I was told I must create a new email address and reregister which I did, I then Tried to load the machines only to be told that it already exists on another business profile.....***, I think it would be less painful getting a different card reader and going with another company because if it is this frustrating trying to set this reader up on my current profile with all these hassles, it really isn't worth the trouble. By far the worst and most frustrating service provider I have ever encountered.
