MTN - Big Company, small individual.

Since April 2020 I tried to cancel one of my 5 contracts, for my daughter who had left for Amsterdam, with MTN. After approximately 15 e-mails between us, my daughter who was visiting, went into an MTN branch and successfully cancelled it in November 2020. Subsequent to this, I have demanded MTN to refund the months that were invoiced and paid by myself since April which amounted to just over R1 500.00. i have sent at least 4 requests via e-mail. Guess what? Only one computer generated and no other reply from them. This is most obviously a large company ignoring a small individual. My last e-mail to MTN was that I demand my refund by 1st March 2021 otherwise I will have no other choice than to take the matter up at the Small Claims Court in Pretoria. I will not give up this fight.
