I called in today to dispute my final bill with you all because I was charged a huge bill which I come to find out is due to the fact that I was on a plan that was discounting me every month but then at the end when I canceled services, all the discounts were just charged upfront. I was upset because this was not explained to me when I signed up for the services. In fact, I never actually signed up for the services. I was with a different company beforeand they closed down and I was immediately sent to this company. All of that was what I originally called upset about, but then I spoke with an agent Who made me even more upset. This agents name was ****** and she continued to call me maam, even though I corrected her and stated that I was a male. I am a cis-gendered male who was born a male and identify as a male. My voice is just high and I had to correct her numerous times because she kept referring to me as maam. I then requested to speak to her supervisor and at first, she stated there were no supervisors to take the call but after I informed her that I used to work as a supervisor and a call center I knew there was. The supervisor I spoke to was named ***** who showed no empathy statement when I told her about being misgendered by the previous agent. All she said is that shed put in a ticket. She also informed me that a final bill is a final bill and nothing can be done about it. I again informed her that I was never informed that I would be charged this lump sum if I decided to cancel services and she stated that I would have agreed to it on a call. I asked if she could review that call and she stated that she could not find the call because it was from years back. So she has no proof that I ever agreed or that this was disclosed to me on that call, shes just assuming it happened. My complaint is that I want a refund or at least a partial refund because I was charged an exuberant amount as my final bill since they added everything that had been deducted.
