I'd been using Square for my small business for years. I'm a fine artist and sell my art in festivals across the US. I don't have a 24/7 retail store so my sales are sporadic. There are times when I can go months without a sale. Most clients/collectors prefer to pay by check/Venmo/Zelle. I sold two large original paintings last Sunday in a festival in Palo Alto, CA. Both clients hose to use credit cards when I arrived to deliver the art to their homes. I processed the charges and was given an APPROVAL by Square app. I installed both paintings and then left to drive 500 miles back to my studio. The next morning I recieved an email from Square notifying me that both charges were suspect. They needed me to answer 17 questions to the best of my ability about both clients. I did. Within 24 hrs the next email came and said my entire account had been DEACTIVATED without any specifics as to why. They recommended I refund both clients and seek alternative payment from them. Both clients are extremely wealthy and living in multi million dollar homes in one of the most affluent areas in the US. These sales were 100% legitimate and whatever 'overnight review' was done to determine their validity was done in error. AND there is absolutely nobody at Square that I could even talk to! Once they deactivate an account the phone number used for the account is put in a DO NOT ANSWER list. I was only able to reach customer service by using their online chat and after reaching several very friendly but completely uninformed agents I had to give up. It's been a week now and after writing several emails trying to receive help on how to best proceed to their customer service I still have yet to receive any information. Nobody is home! So, my biggest concern is that they can actually give you approval for the charges and then 2 days later just decide (or an algorithm decides?) they are too risky to process. Long after you've left the merchandise with them! I can appreciate that there is a system in place to deal with fraudulent activity and IU can understand the risks...but neither one of these clients were contacted in any way by Square. Any real investigation would have revealed that both parties were extremely wealthy, using these same credit cards successfully routinely without issues. Square actually punished me, the business owner for making two legitimate sales! Causing me to go through hoops of embarrassment, hours of confusion as to why and now perhaps another week or two to wait for refunds to be processed and then alternative payment received! Still can't even reach a live person to talk about the situation. Fortunately, both clients were understanding and are offering alternate payment solutions. But Square...is the WORST! Avoid using them at all cost as clearly in this case...getting an approval from a charge is meaningless and at any time your account could be burned to the ground for simply making a sale or two.
