Terrible customer service!

Telkom has the worst customer service, I have been battling since April to get hold of any one that can assist me with my faulty laptop that only worked properly for a month. TELKOM says they don't deal with laptop repairs, their staff is *********** as I spoke to over 5 consultants, eventually I saw the warranty details on my laptop box, which I then contacted Lenova, and said that they can't help me with my laptop online as they don't know what's the problem, I must take it to a partner to fix, this is ridiculous. A brand new laptop that isn't working. I tried calling telkom again, the Sales Consultant by the name of Thandeka, hang up twice as I was trying to explain my situation, I then called back and the consultant said, her manager would give me a call back. By my surprise I haven't received a call back. I am paying for a laptop that does not work, this is ridiculous. As I feel I do not want this laptop any longer. They cannot offer me an exchange or upgrade, non of the consultants have been any help thus far. I would not recommend this company to any body. I'm frustrated as I cannot do any work!
