Poor service

Over the last few months I have been having issues with my connectivity. From when I upgraded to the 5G contract, I have not moved the router from where I found the best reception to t tower that is about 1.3km away. Since about August, I have had to move the router around the house looking for signal, as the tower I usually connected to had issues and had to connect to a tower further away from me. I called the call center on numerous occasions to ask what the problem is, and got answers like its loadshedding, which damaged the tower, to the tower is offline and needs to be reset, to my sim is faulty and we will issue you a new one, to my router is faulty and we will issue you a new one. To date, nothing has been done. I have called the call center and all they say is reset the router or that they will escalate the issue and still nothing gets done. If you guys cannot fix the tower, or if the tower is too congested install new ones so that the people can connect instead of paying for a service that is up and down all the time.
