RAIN 5G worst product and service provider

This is my second post with regards to the worst product and service provider namely Rain 5G. I am a subscriber on the optimum 5G package for R999.00 per month promising signal strength of up to 200 MBPS. From the end of April my download speed dropped from an average of 160 MBPS to between a maximum of 5 MBPS to 14 MBPS. Despite several requests to their support for assistance which were ignored I posted on Hello Peter. Thereafter someone contacted me for assistance on private reply. They thereafter dispatched technicians to my residence who indicated that the problem was not with the router as it was optimally installed and on the roof of the premises. I was informed that the reason for the poor signal was either poor maintenance on the tower or usage. By usage they mean that Rain is signing up new clients daily, which the infrastructure cannot carry. This has led to poor signal on my side. They are therefore signing up new clients at optimal rates promising fast connection speeds knowing that they cannot perform. It has now been 2 months and 7 days with the same pathetic signal. Their support has been limited to asking me to send them different screenshots of the poor signal and asking every now and then whether the signal has improved, which it has not. I have asked them ion numerous occasions to contact me telephonically which they promised to do, To date no call has been received. They passed a credit of 50% for the month of June and still expect me to pay half the subscription although my signal is between 5 MBPS and 14 MBPS. I am therefore paying for a racehorse but getting a donkey. Their lack of interest in resolving the issue has placed severe financial pressure on the household. Business meetings that could be virtually attended, and was a main reason for subscribing with them, now are physical resulting in huge travel expenses being incurred as they involve travelling out of town. In short if you wish to avoid paying for an optimal service and get the worst possible connection do not support these people. What they are doing is false advertising and taking the public for a ride. They are enriching themselves without any consideration of the impact their actions have on their clients.
