Contract cancellation

I requested the cancellation of my contract on 27 March, and the cancellation was only finalised on 10 April. When I initially contacted your call centre on 27 March, the agent clearly advised me that I would only be debited a prorated amount of R56 on my next debit order date. However, to my surprise, an additional amount of R350 was debited from my account without explanation. Furthermore, I have been charged a cancellation fee, which I strongly dispute. At the time of signing up, the sales agent explicitly advised me that there would be no cancellation fee. In addition, I was signed up for the incorrect product, which is the primary reason I requested the cancellation. I understand that the delay in processing my cancellation until 10 April was due to MTN reviewing call recordings, which confirmed that I was not provided with the product I had agreed to. Given this, it is unreasonable and unfair to charge me a cancellation fee for a contract that did not reflect what was originally promised. Based on the above, I request the following: A full explanation for the additional R350 debited from my account A reversal of the cancellation fee A refund of any incorrect charges app**** to my account I trust this matter will be resolved promptly. Please treat this as a matter of urgency.
