failure to unblacklist my contract phone

Couple of weeks ago I misplaced my phone then I called the call centre to have both my sim and phone blocked till further notice, the next morning I got my phone back and again called the call centre to stop the blacklisting then the consultant said no it was only my sim that was blocked so I must not worry she already unblocked it.few days later I got an sms that says my itc ref no. For my cell is ***2 then that's when the services on my phone were suspended. I've been calling and going to cell c store in randburg for the same thing for days now but till today my phone is still not working,I've emailed what was requested from me but still I don't have a phone but I know month end they will debit me for this phone but they fail to unblacklist it.I called again yesterday and the consultant said they send an sms that says my phone was unblocked but when I got home my phone is still not working so I think I should involve my client tel legal team maybe they will be able to assist me coz now I'm fed up with cell c. I want it out of my life.if they don't unblacklist my phone today I'm taking this matter further.they are unprofessional and incompitent and I want cell c out of my life
