Wondering if anyone else has had this problem...a customer wanted to buy a bracelet but only if I could take a credit card...I excitedly answered yes! She purchased an $80 piece and the sale was approved by square..she signed and walked away smiling wearing my beautiful creation. About 15 minutes later I checked my email for confirmation as I always do and found out the woman had cancelled her payment to me! I contacted square and they said there was nothing they could do...they were only a go between customer and bank...no address, no phone and only a scribbled signature...I lost $80 to this scam artist...lesson learned the hard way...always get some sort of Id phone name etc...beware of square!
