Telkom bad isp

Telkom hmmm a company I once looked up to a company I thought I could trust. There are many service providers out there but I decided to put my trust in TELKOM when selecting my internet service provider. So I have taken out a unlimited home package adsl line 4mbps I was happy with my service I have gotten from my adsl line for the 2 years I was satisfied but come to end of 2019 I have been FORCED to take a lte service I have gotten a few phone calls about them asking me to switch to lte I refused of many times but one day I get home from work I received a call from a technician informing me he is on the way to my home I asked him why he rep**** telkom has sent a lte router and we are cutting the adsl line I was unhappy about this but had no choice cause I felt threatened as i was told i wont have internet which is a must for us to have. Anyway new router installed and from then I have been receiving very slow internet compared to my adsl which I used to receive my full 4mbps I noticed that the new one is slow so I decided to do a speed test and notice I'm only recieving not more than 2.5 mbps almost half the speed I have been monitoring the speed for a few months and I have come to realised i am being ****** I have called and complained many times all I got was we will lodge a complaint to technical department then few days later getting sms that the issue has been resolved they do not do anything about it cause everything remains the same I am paying full amount every month for half the product telkom must sort this out I am a paying customer.
