Useless Staff at Telkom

I have taken a laptop on contract and after 6 months it is faulty. Phoned the call center several times and was eventually advised to take it to my nearest branch. After standing in a quee for half a day my nearest branch states that they do not handle faulty devices and gave me an insurance number to contact. After phoning the insurance they state that I must email them a proof of purchase. I told them that I do not have such a document as it was ordered online and on contract of which they advised me to get it feo. Telkom. So back from the beginning contact Telkom customer service. After several times being transferred and cut off I was told to speak to the online department. I phoning them I was advised to send them an email at ***. The email came back undelivered as email address not found. I had enough. 2 Days to try and sort this out and I got absolutely nowhere. TERRIBLE SERVICE!!! I will not pay this account and I do not even care if the blacklist me. Let see maybe they will contact me when they realise I am in arreas...
