Telkom fails again!!!!

Last night my phone was ******. It is on a Telkom mobile contract and so I quickly rushed to the Tekom shop to blacklist the phone, I spent 30 minutes on the phone in store to a call centre where I was then told that blacklisting is not something they ordinarily do and that some sort of grievance had been logged and thats all that could be done. Meanwhile I was calling my ****** phone and people were answering the phone and Telkom could do absolutely nothing to help me. The police also told me that it is common practice that phones get blacklisted with their service providers after being ****** so that the phone cannot be used any longer. I had no control over having my phone ****** and now Telkom gave me no control over who was using my phone. As per usual with Telkom I felt helpless, disappointed and generally let down. I have still not received my upgrade since my last complaint and having waited 3 full months. This means that I now have no phone and no way of getting my upgrade. The general lack of interest, care and assistance from anyone at the Telkom mobile store lets me wonder how they are successful and why this sort of business practice is even allowed.
