terrible service yet again

I made a complaint, was called back but still not assisted. The person did not leave me her name or number. Its going for 6 weeks now that i am trying to do an upgrade on my account. Together with all of my last 100 attempts, day before yesterday Alberton CELLC told me to contact legal. They dropped the phone in my ear right in front of the cellc lady. She hoever checked the system and said number *** is outstanding R333.81. Today the owner of the number went to Cellc Newtown mall to pay but he was told a R150 was to be paid by another number under my ***. I am now ****en sick and tired of cellc useless customer service and want to speak only to the head of customer services.
