Bad service

About 4 months ago my pay date changed from the 30th to the 20th, I pay via eft and thus paid it earlier than usual . From then on every month, a few days after paying my account MTN suspends my account I then have to take time out of my day to phone and sort this out proof of payment is emailed automatically after each payment. This has now happened three months in a row. Because MTN is incapable of reconciling their accounts correctly I THE CUSTOMER am inconvenienced every month. I am now going to share this post on any social media site ****ible. Your service leaves alot to be desired I am so upset that I am seriously considering a new service provider. When I told one consultant to fix the problem or I would cancel I was told sure but you will need to pay your contract up no appology or empathy just rude.
