Cell c pathetic customer service

I have made a complaint on this platform approx 6 months ago to resolve a query ( where they are over charging me for a contract taken out in 2022 . You have read correctly . They started assisting , promised that they would do a refund and change the rate and despite this have not done so . The social Media team have reached out initially yet the billing department has not been able to execute what they supposed to do . Someone at the sm team have escalated it again to the billing’s department a week or two ago to correct . And no and behold a generic email from customer service saying that they can’t deal with the matter as they have. Or been provided with the details . And this is with a department within cell c escalating it . This email wa forwarded onto the social Media team dealing with it and still waiting for a response from them . My contract term will be over and the query still won’t be resolved . I have not met a company more *********** before .
