Bad service (Telkom)

I am very unhappy with the service that I am getting from Telkom Three weeks ago I went to Old Mutual only to find out that I had an outstanding account with Telkom. I then went into one of Telkom's stores (Cape Gate) to enquire. They checked on their system only to find out that I do not owe them anything and have no outstanding amount. I then ask if I could speak to billing department, at billing they told me that I own them nothing and that my account was paid up. I asked if they could send me prove of this via email which they did. I requested a settlement letter which they send me, but later informed me that I must still pay R3475.21. I then asked them why I must still pay, after they already send me emails stating I am paid up. After sending emails, but got no feedback I decided to pay the amount, but now they don’t want to give me a settlement letter to say that I have paid up this account. I'm really disgusted with their bad service, they ignoring my emails. Its going on like this for the last 3 weeks now. My patience has been tested to the utmost.

If I don't get any responds, I will definitely take this matter further. Its unacceptable what I had to go through with these people. It seems as if they don't work on the same system. But that's not my problem, I need assistance no later than today!
