MTN Complaint

On 31 July 2019 I took out a contract with a franchise store in Langebaan. The contract gave me 50 airtime minutes, 500mb data, 500mb data after midnight and 50 sms's for R229 per month. This month I noticed that I only received 250mb data and when I queried this at the store I was told that I had agreed to a telephonic conversion, which gives me 250mb data, 250mb social data, 50 minutes airtime to any MTN number. I do not recall agreeing to the new package as it certainly does not suit my needs. I sent a letter to MTN customercare on 18th January and got a reference number and a reply that it would possibly be dealt with within 8 business hours. A number of days later I sent another message as I had not received a reply. Eventually yesterday I was advised to phone *** which I have been trying to get through to most of this morning. I want my original contract reinstated as I am extremely unhappy with what I have been given. After speaking to a few people we all agree that these promotional phonecalls are like listening to a recording ,they speak so fast that half the time you cannot understand what they are saying and sometimes the consultants are just rude. Hopefully this complaint will reach the ears of someone high up at MTN who will then contact me on ***. Regards Carol Shaw
