Line on new contract still not working

It is such a pity that a technical problem will cause excellent service from the store sales lady to completely make me regret the decision to take up a new contract with Telkom. I signed up for two new lines and they were issued on 21 December. One line works and the other one does not. The lady from the store has phoned me three times to update me that there is still no resolution. This is frustrating and absolutely appalling! Of all the network providers, I chose Telkom, these were gifts for my children, I have one happy one and one extremely sad one! In spite of the store sales lady trying to assist, I find that the problem is obviously not to do with her, she has done her job, and however lines are activated has not! If this matter cannot be resolved ASAP, then this contract must be cancelled and I can get a contract from a service provider who actually is going to provide a working service!
