No service from MTN Head Office

Good morning. My name is Marinda Greyling and I have been a client if MTN for years. The service received lately is substandard though. I have renewed my contract in Nov 2020. According to tfe Mega Gigs S I am supposed to receive 4GB a month. Which I did in tfe first month and since then only 2GB. My MTN store has been helpful and from February they have tried to sort this out.......NO ONE answers any e mails. There is a whole trail of all the e mails sent. Furthermore the call centre is absolutely pathetic. Puts you on hold and don't get back to you. Or use the excuse that they are not on line. My further complaint is that I took a mobile WI fi ****le in April. It is still on offer. I am supposed to receive 1GB per month......but guess what......RECEIVE NOTHING. And the same story.......NO feedback from anyone at Head Office. You are renewing rugby contracts but give no service to your clients. If it was not for the kind people working at the store in Jacqueline Street Alberton I would have not wanted to stay with MTN. As a business you can't only care about the big contracts.......the small people are just as important. Can SOMEONE please help????? Although I look at the reviews and the company is not answering any of them. Do you even care or is it fine to have so many unhappy clients? Are you using the pandemic to hide bad service and wrongful appointments. No one that cares at MTN.
