!!PLEASE FIX MY LTE SPEED!!

Received my Afrihost LTE router last month, the first month was great, internet was fine, on the 70/50Gg package. since the 29th of August the ping went up the download speed went down, my ping tests shop over 100 ping, and 1.9Mb/s download speed, all day, not peak hours 24/7 the download speed is the same, low low low I have phoned in 4 times, and received the exact same advice, changing settings restarting, APN settings, getting told Telkom will get back to me but nothing has happened, i will be cancelling in the next few days and sending the router back, its false advertising.
