LACK OF SERVICE LEVELS IS PATHETIC

Its been 4 weeks now that I am trying to get an upgrade done on my cellc account. I called and was told I cannot do an upgrade since there was issues on my account. I explained to about 3 agents after about 10 different telephone attempts over 5 days, week one of my upgrade mission, that when I took out the contract originally, it came with 3 sim cards and 3 phones. One phone and number was for myself to use, the two others were for my bro and brother in law. Unfortunately my brothers debt orders did not go through and I was subsequently blacklisted as I was the main member. After many attempts I got CELLC to divide up this one contract to 3, wrote in a motivation letter, each of us had to write and hand in an Affidavit, send in everyone's ID documents copies, and also supply bank details of of brother and bro in law so that their accounts debis could be taken off directly from their bank account and thus this contract was now split into three. Now when I want to resume my contract ans upgrade, I am told there are still some issues no my account? I phone in multiple times and speak to consultants who promise to call me back. I phone in day after day, speak to someone new everytime
