3 months and 90 calls later, My issue is still not resolved!

In November I called telkom to upgrade my line speed to 10 Mb/ps. Shortly after this request my internet stopped working. When I called telkom again regarding this they said it was unrelated to the change in line speed and that the issue was due to my router needing to be reconfigured. The lady on the phone could not give me a correct ip adress for the telkom server so i could reset my username and password. I found an ip adress that worked on google, which also said that the ip adress the lady was giving me was a very old ip adress and telkom no longer uses it. My line speed never changed to 10mb/ps so when i called again several weeks later, a consultant tells me that 10 mb/ps is not available in my area, this is after the consultant i spoke to when i changed my line speed checked availability in my area and assured it was available. So I settled to upgrade my line speed to 8Mb/ps. Till today my internet speed has never been 8Mb/ps. Everytime i check my line speed it is 4Mb/ps. I’ve logged a fault twice regarding my line speed being 4 Mb/ps but the faults were never resolved. Apart from a few phone calls from Telkom technicians asking if our faults have been resolved no further help resolving our line speed has been issued. I think its highly unfair that i have to pay for an 8Mb/ps line when i’ve never received that speed till today.
