Cell C WORST COMPANY EVER

I have been fine with my cell C up to about 4 months ago... Have been having networking issues due to them canceling there roaming ability in the North west area with MTN, they have been promising to get it fixed by putting up a new network tower but still noithing has happend in 4 months... They keep debiting from my account and i keep logging issues but they never get back to me!! The last email 3 months ago said that i can contact the cancelation department but the number does not exists!!!!!!!! The last agent I spoke to had an excuse that there head office was being revamped and thats why they have not contacted me with my issue!!! CELL C IS USELESS AND I WOULD RATHER USE ANYTHING ELS THEN THEM AGAIN!!! I CANNOT CANCEL MY CONTARCT WITH THEM OR ANYTHING WORST COMPANY EVER i would advise anybody with Cell c or thinking of going to Cell C to rather never use them!!!!
