Bad service from rain

I got a rain sim data sim while staying in gauteng in October 2022 the in November I relocated to Limpopo nd I called rain to inform them that my wifi was not connecting nd the guy that helped me told me that rain has no coverage in my new area. I then requested for my SIM to be disconnected as it was of no use to me that was in the 10th November 2022 nd the guy assured me that there will be no charges. Since beginning of Dec I've been receiving messages from rain saying they are trying to debit my account nd last week they managed to debit R265 nd then sent me another message saying they will debit again before 31 Dec. I sent an email to support to request help but an automated message came back saying that email no longer works yet it's the same address they have posted on their website. I tried to contact them through calls and kept holding till I ran out of airtime. I tried Facebook and the response I got was that im billed because my account is still active.i tried again to call them and the gentleman that assisted did confirm that my account is indeed active. Im very disappointed in their service I was assured that there will be no charges nd that my SIM will be deactivated as of 10th November to my suprise I'm billed for a sin I'm not using as I was told it will be deactivated. I requested to be called back by a superior and the guy(Kunal) promised that I will be called back the call cut off as I ran out of airtime but no call has come through I've been waiting since 19:53pm
