Cox fraudulently doubled billed elderly seniors and harass them oaks pa

Any advice my 86 year old mother is being harassed by COX she has paid them double for 5 years. She lives at senior center and the phone internet and cable are all included in her monthly rent my mother did not know and she proceeded to pay for internet TV and cable also to cox. The facility has a business account with Cox and mom had a residential account as she transferred serves to facility  after seller her home for a while she paid for services at her home and to facility and also paying in rent so paying three times. My mother wanted Cox as she had alarm on her home.  Long story but I did not realize till I called for a seasonal hold to stop having payments for 4 months while she was hospitalized they agreed to an almost 400 credit for four months my mother was hospitalized. Three representatives, three different times promised on recorded lines with confirmation numbers of the refund that I never received on my credit card. The representatives noted previous one did something wrong and corrected it. In order to get the promised credit. I spent over 30 hours calling different numbers and going to store numerous times. They did not understand due to having been a provider of residential cox and noting to go to business cox. I then later realized that she not only should be refunded for those months as promised but cox should never had a residential account as she was paying facility for duplicate services. I disputed several charges totaling the amount promised and confirmed to be refunded and disputed on my credit card. My credit card was successfully refunded and almost done with review and permanent credit when cox billed my card again after her residential services were officially stopped. They billed her for the charges I disputed on my credit card and she paid them along with 25 fees on each of 5 charges. My mom has dementia and noted she did not want bad credit I also asked facility not to give her mail from Cox as they sent me more bills for disputed charges along with late fees which I have ignored till I found out where to go to stop Cox from stealing from my mom. I’m sure Cox does this to many. I have spoken to so many different people on phone and in person and not one fixed the problem so I disputed on my credit card giving confirmation numbers of promised refund.

I want promised credits back from Cox, but my -mom paid Cox again along with fees as they sent a threatening letter. Now I cannot dispute on my credit card, mom paid by check. Any advice my 86 year old mother is being harassed by COX she has paid them double for 5 years. She lives at senior center and the phone internet and cable are all included in her rent she proceeded to pay it also to cox. Long story but I did not realize till I called for a seasonal hold to stop having payments for 4 months while she was hospitalized they agreed to an almost 400 credit for four months and three representatives promised on recorded line with confirmation numbers of the refund that I never received on my credit card. I spent over 30 hours calling different numbers and going to store numerous times. They did not understand due to having I’ve have tried to resolve this with Cox but cox employees and supervisors keep passing the ball

I prefer to go through and agency such as FCC or BBB to help my 86 year old mother who has been double billed for 5 years a full refund of not just 4 months while in hospital but 5 years of payments which at the time I did not realize she was already paying in her rent to faculty and again to Cox is the worst most scandalous companies I’ve seen in my entire life.
