Square Inc Enemy to Merchants San Francisco California

Square Inc does NOT care about, nor protect the Merchants to who pay their fees and bills!  

We are a health practitioner's office who sadly encountered a disgruntled client who told her visa/bank she was due a refund on a wellness package she used but woke up one day on the wrong side of the bed. We provided our signed receipt - THROUGH SQUARE - stating "no refunds, credit only" AND pages of signed contracts stating the same.

We have been informed by Cameron in Dispute Services "we are in contract with all major credit card companies that they have the final say".  So apparently it doesn't matter the merchant provided signed contracts in many forms.  Now we are told there is no recourse but to go sue her.  So what's the point of having customers sign paperwork if your own merchant services company won't defend you?  OR worse yet, gets the information required and allows the disgruntled party to get their money back no matter what?  DO NOT USE SQUARE!  They seem all good till some freak decides to want money back and not be accountable for the contracts they signed.

today we went back to our vet and told them we wanted our money back because we didn't like their diagnosis or assessment of our dog's health.  They laughed in our face and escorted us out.  DO NOT USE SQUARE!
