No Service at all

Good Day

i reported a fault on my telkom adsl line 3 times all 3 times they said the problem was solved, but not one of the 3 times there was someone at my house to have a look at the fault I have a 10Mbps line but get very slow speeds on my internet sometimes as slow as 0.5Mbps but I pay for 10Mbps. I also tried to port my pre paid number to my telkom simcard wich they said i must wait 48 hours for the port to take place its a week now after the second time i went to the store and the porting is also not done as yet.
