Most Pathetic Service Given by MTN South Africa

Most terrible and disappointing service ever. I app**** for a month-to-month Wi-Fi package over a year ago and their FUP is always bothersome so I emailed them and complained on numerous occasions to upgrade me to a higher package which they could not do. However as soon as a year was completed, they decided on their own without my knowledge or consent to downgrade me from their already terrible package to an even more disastrous package where the FUP lasts only for 4 days. I made payment on the 12th of this month to bring my speed back to normal and they tell me although I made the payment, they will put it towards my next month's instalment which is only due on the 07th of every month and If I want my speed to be brought back to normal, I must recharge on the app... What nonsense!!! As I am not in any arrears for my Wi-Fi and they are dictating to me why my speed can't be restored yet they are aware that I work from home, and I need my speed to be constant!... not to mention it is a complete nightmare to cancel your contract with them as they prolong delays purposely just to keep you binded to them. Most pathetic network in South Africa. Will the Ombudsman for customer service please step in to assist me in any way possible.
