I had to pay a deposit of $255 before Rotech would place the order for my husbands simplygo. I paid them. The simplygo broke and I called them to fix it I was told I had to send it back so they could send it to get fixed with no estimate of repair time. I was told while my husband waited for it to be returned he would be given O2 tanks, we got the simplygo in the first place so we can travel as we please. I told them that was unacceptable we were paying for a mobile unit and that's what we needed as a replacement, the person I spoke to on the phone told me my husband would take what Rotech gave him. I hung up the phone and bought one. They came to pick up their equipment Now they want $113 even though the account was on auto pay. I told them take it out of the deposit and send me the balance. Seems they have no record of me paying a deposit, I put it on my credit card so I have proof of the deposit. I am refusing to pay the $113. I haven't received the balance but they keep calling me and harassing me. My question to Rotech is where did my deposit go?
