Telkom bad at Business and LTE

In Dec 2016, I took a 50G LTE contract with Telkom as there is no fibre in my area. There was no additional router cost as it was explained it was in the package and a 24 month contract. had I selected a month2month, there would be router cost. Signal not great, but better than paying for DSTV. In Dec 2017, I migrated to a 100G package, NO Router taken, signal not improved, but all in all, we Netflix, until I further migrated in May to a 200G package and was hit with a whopping R900 cost for a router.... firstly the LTE signal is so bad between 6 and 11 pm every day, that we cannot use the LTE. then I am being charged for a router that is 18 months old. when I call the call centre, it is really NONE EXISTING . TELKOM IS TRULY THE WORST. All I want is the refund for hte router I did not get.
