MTN refuses to refund me

My MTN contract has finally been terminated after 4 months; however, I am encountering difficulties in obtaining my refund as promised by many of the personnel I have interacted with during this process. Despite my calls to the Mondo people, who assured me of escalating the matter due to its prolonged status, I am still awaiting a resolution. MTN owes me R1784.50, and their refusal to reimburse me is based on the argument that the funds should offset the contract termination within 24 months. Despite addressing this with the sales consultant, who originally assured me a cancellation fee of R195, their accounts department continued billing me from July to the end of October, even after confirming the error from their end. The urgency of resolving this matter cannot be overstated, as the promised refund is rightfully mine and should be promptly deposited into my account. Their customer service personnel has started dropping my calls every time I ask to be transferred to either contracts, collections, or accounts. The following people from Mondo have been trying to assist, however, MTN seems to have an upper hand because nothing has been done up to date.
