Telkoms pathetic standards of delivery

When Mondo contacts you to offer you a contract with Telkom its all good and well when the contracts arrive. The disappointment starts when the ****als and Sim cards are not working and you contact Telkom they refer you to Mondo and mondo feedback is that you should restart, which is what I have been doing for the past 3 months restarting ever since I got this contract and nothing is working clearly you can check the usage and then Telkom is quick to send bills who is responsible to take ownership of the **** you sold me and why should I be liable pay for something that I have not benefited from.
