Square Up Credit Card Processing - White Square that goes in your phone No Way to Contact Square When Someone Breaks into your account Internet

Like others on here, I am getting fraudulent charges and emails stating that a customer is disputing the charge.  Unbelievably, I have no way of contacting Square.  They have a customer service number that can only be reached after you sign in.  I cannot sign in because my account has been compromised, and have not received a password change sent to my email despite 4 attempts over the last 3 days.  I have tried filling out their online contact form 4 times and have received an email days later stating that someone has tried to reach me but got no answer.  I have received no phone call.  There is no customer service number for me to return.  These fraudulent emails say they come from squareup.com.  There is no contacting Square whatsoever, and they have my bank account number and all my personal information.  DO NOT USE SQUARE!!!  I received an mail stating there was a debit card added to my account, even though I don't own this debit card...and the fraudulent charge was made after that, but I am getting hit for it by Square...And Square gives me no customer name, nothing.  Just the amount and date.  It was made at 4am.  My business is not open then.  Obviously this is a red flag?  USE PAYPAL!!!
