Pathetic Service and Network Speeds

Pathetic and shocking experience feom MTN. I signed up for a 10mbps FLTE home internet. They checked my coverage and said that the Ermelo region in Mpumalanga is covered. After a month of use I was getting speeds on average of 7mbps which I can accept. For the last two weeks however the speeds are on average 0.2-0.5mbps!!! Absolutely shocking! That is speeds from the 19th century. After over 20 calls to their call center and 5 reference numbers later I have received no answers. They have re-set the router around 20 times as well for God knows why. Clearly they have no clue what they are doing. Their social media team is just as clueless as they are doing the same generic things to rectify a problem that is clearly not with the router! I have spent around r1000 on data over the last two weeks! This is absolutely pathetic service from MTN and if they think they will debit my account further they are wrong as I am going to cancel the debit order and throw that useless router into the bin. A client lost because your customer service is pathetic and so is your network. Hellopeter if you can assist I will appreciate it. Will never recommend MTN to even my worst enemy.
