Urgent help needed regarding a matter involving Telkom

For the past 3 months I have being having a WI-FI problem I have reported it many times and every time a technician came out they gave us a different story. My contract with Telkom is only a year old; I took it out in May 2020. I have more than 6 reference numbers could be even more that I have not noted down. The first time I was told by the technician that the router was a problem, I took the router to the Telkom office and they tested the router and told me that there is no problem the router is perfectly fine. Every other time going forward, I was told by the technicians every time they came out that it is the cabling, the extension, the earth protector for the router and then finally the router is the problem again. I have reported so many times and until today unsuccessful and still sitting with the problem. We cannot even do a speed test and if we can we are getting a 0.46 or even lower speed for the Wi-Fi. We cannot even work properly and it’s costing us more money to keep on buying data for our phones whilst sitting in the house with the Wi-Fi on. Our Telkom bill is getting paid every month without any hassles but we are not getting any help from Telkom at all. Recently I was told by the technician that the router is not right even after getting it tested and that I need to buy a new router that will cost R1500.00. None of this is our fault, when I app**** for the WI-FI Telkom came with the router and put it on for us. I have so many names of technicians, managers, references numbers and I even have proof of emails that I escalated the problem to higher in Telkom but to date no assistance to the problem is being solved. Yesterday I had a technician from Open serve come out to our premises, he didn’t even get out of his van, we had to go the fence and speak to him through the window, all he said that he received a complaint, I indicated that we still experiencing problems, he continued to sit in his van and tells me that he is trying to get hold of his manager, then when I said I escalated the matter further he tells me that Telkom has 5 CEO’S apparently, I questioned him how is that possible that a company has 5 CEO’s. He then told me I must give him the name I escalated the problem to and he will phone the person, which I refused to indulge to him. Not long after that I received a sms from Open serve/Telkom stating that the problem is resolved and closed. This morning just after 9 the WIFI went off until now, so I can’t understand what the problem is. I really need help and assistance
