Massage Envy review: billing at branch location

My future ex-wife was using my HSA (Health Savings Account) credit card without my knowledge to purchase massage services, provide gratuities for services, and even purchase gift cards for her friends. None of the above were medically necessary. When I brought this to the branch managers attention I recieved little to no cooperation in getting these charges reversed. She has been a member there for quite some time and has developed relationships with the staff, for which I suspect may be playing a part in amount of cooperation in getting. They went so far as to accuse me of harassment, meanwhile it is my money set aside for my families doctor/hospital bills that are being used for there own tips.
