Worst service ever, no knows why my phone is blocked

All of a sudden I went from 1700 minutes to 14 minutes in total, 0 data and 0 sms's where I had unlimited messages. I did a upgrade in January where the consultant said I can stay on the RED package, just to hear when I went to pick up my phone I can stay on that contract because of a credit score, I never had any late payments nor did Vodacom ever try to deduct and that it was unsuccessful. I phoned customer care and they said my credit score can be lifted in order to stay on the same package, but no one in the shop dared trying to really assist me, they just gave me the option to stay on a small package that didn't have any of the RED benefits (I mean if the "expert" says that is all you can get you will believe them, they are the ones that really knows). Today my phone is blocked, I can't receive or make any calls, my data and minutes was ****** and NO ONE AT COSTUMER SERVICE CAN ASSIST ME, THEY SAY THEY REALLY DON'T KNOW. And also one guy had the nerve to say that there is no money in my bank account to deduct the debit order. WHAT A JOKE, I'M SOOO DISSAPOINTED THAT I DID'NT DO A SIM SWAP LIKE I WANTED TO FROM THE BEGINNING. Maybe if we start complaining on Hello Peter we'll get a better response as calling the call centre.
