Terrible service

On 28 June 2015, I requested a blacklisting of my son's phone as it had gone missing . We subsequently found the said phone later from someone whonhad ****** it. On 29 June 2015 I called cell c to unblacklist the phone and was told to fill in the unblacklisting form, which I did. I faxed and emailed on the same day and was promised that it would take a few hours to 24hrs. I called on 30 June 2015 and was now told that a technician would call me back but no one called. On 30 June I received a sms stating that someone would call me to resolve my problem within 48 hours , nothing happened. I called cell c on friday, 3 July and I was told that someone was going to call, but no one did and so I called again on Saturday same promise was made. Today 8 July I called and I sti get the same response that someone is working on it. This is unacceptable. My son cannot make call or receive calls, send messages or receive messages.
