Telkom mobile complaint

The service i got from Greenstone mall branch is very poor. An agent in the store sold me a contract line and what was promised is not what am getting. Was promised to get 10gb for the first 3 months , a certain number of calls to other networks, to use my prepaid telkom number on this new contract , free whats app, free calls telkom to telkom, to keep the contract fixed to what am paying and not to charge out of bundle charges...this was never done. Its the 2nd month having the contract and am being charged for everything. I signed for a contract of R369 and am paying R700 more. Am wondering what the contract is coming with.Been to the store 2 times and nothing has been done so far. Been calling Telkom to no avail. I took the contract on the 29th of July and they are counting July as the first month. i am regreting porting my number from MTN.
