Wrong billing and bad customer experience

<p>I am tired of Telkom I have had the query for 4 months now and nothing seems to happen I have been debited R861 instead of R263-78 for something that I have not used that was sold to me wrongly I sent the device back to them in august then I get told that I have used it in September how do I use the device that was not with me and whose fault is it that they took time to change my number to prepaid ,I am not willing to pay so much apart from the R150 contract I took and if they have problems they shood go back to velocity who is their partner ad again the lady from billing sent me an email stating that I should pay R261 when I sent her back the email no response no nothing her name is Cleo Makhubela ,I would like to be refunded and get a response by today or I do a reversal and your team will debit the right amount from my account .</p>
