Breach Contract and terrible service

I am utterly upset at the horrible service I have received from Telkom in the last few months ,

I have taken two data contracts with them , one of which is a 5gig and a 10 gig. every month I receive data on both routers on the 1st but they will both become depleted in less that 8 days. I have tried calling them to let them know that my data disappears without a trace but they keep telling me they are investigating , I cannot be continuously be asked to check the settings on my phone when I know for certain that it is their service that is at fault.

of recent , I bought an additional 2gig on Friday the 11th of January at 8pm or so but I woke up to a depleted data the very next Saturday morning even after I had switched off my phone when going to bed.

I logged calls and all occasions I am told my query is still under investigation.

I am very unhappy as I remain with no data but a monthly debit order that goes to Telkom .

I would like to cancel this contract effective immediately without any penalties because I have been paying for no service . Telkom has failed to keep their end of the deal.
