Still cannot upgrade because of profile!

It has almost been 1 year since my upgrade date, and I am still being told I cannot upgrade because of my profile rating that has dropped. Last year I had fought the fight and decided to wait a few month and try again.<br> But again was told today the same...I have never missed payments, I have three contracts with Vodacom with a monthly account of R900 + and still I cannot get a profile upgrade?? I do not understand why loyal customers are being treated like *********, I am disgusted to say the least, and fed up. What must I do to get a profile upgrade???
