Worse Service ever..I regret taking explorer contract with MultiChoice

I reported overcharged on my account they promise to fix it, that was 2 weeks back, last week friday I called to check if it was corrected, the lady who help me she said everything it's sorted and I'll receive my money back in the next 3 days, today I check my balance nothing was fix, those guy gave me explorer for 499 for 24 contract, now the changes price, if they don't fix the price lock, am cancelling that explorer contract Warning to other people that R499 you see on the board and TV doesn't exist, you take contract after 6 months they will increase without your knowledge My Ref for today, ***1/I 332 Abongile I spoke to, and she refused with her surname
