My bill is suddenly 30 Thousand Rands

<p>Good Day</p> <p> </p> <p>I am a telkom mobile customer with a very serious complaint. I have been with telkom for the past four years and have relatively okay service. Where possible they would rectify. However they have outdone themselves this time. I took out a cellphone contact for three devices at the end of 2015 with my first bill to be 2016. I travelled at the time and came back and made the initial payment. I then changed bank accounts and called to have the bank details changed. In May of 2016 no debit order went off. I called to inquire they said that the payment would go off on the new account. I have called repeatedlt since to make arrangements to pay my account. One lady responded to me via email while I was at work and I was unable to take her call. I emailed her back requesting a call back which never came. I called the number she called me on to no avail. I emailed her again and eventually, I called on the 28th of September only to be informed they have been trying to debit my old account and as a result they have had to write off my account. No attempt was made to contact me to find out what was going on. No attempt was made to inform me that "I requested a cancellation" no proof of my request to cancel was provided to me and now I am sitting with a 30 thousand rand bill against my name. Telkom Mobile please can you inform me where this came from and how seriously you take your customers. What is the point of having a customer service portal if they dont relay information. I want it rectified immediately. </p>
