Vodacom is my worst nightmare

On November of 2018 there was a promotion of RedDeal Offers which was a Black Friday special I had a lot of airtime and so I bought the data because the deal was satisfactory. On January 2019 things went south as I received a bill from Vodacom stating that I owe them R1320 or so, and I was shocked because all this time I thought I bought the data once with my airtime I did not know it was a continuous promotion. I was flabbergasted when I contacted Vodacom and they stated that the offer was continuous. I had asked them to please cancel that offer as I was not able to afford it and they stated that the offer was “canceled” and I received a reference to confirm that. But three months later I received another bill stating that I now owe Vodacom over R3000 i proceeded with the same precautions as I did before and I received another reference stating that the offer was canceled and I would only pay the R1320 which I began to pay installments because my sim cards had been blocked but when I started paying the sim cards were unblocked. Fast forward to 2020 I received another bill stating that I now owe over R6000 that’s when I realized that enough was enough and I went to a Vodacom store and they contacted the call center and they gave me numbers that I should contact, I was given the runaround and the problem was never solved. To make matters worse Vodacom has yet again BLOCKED my daughter’s and myself’s SIM cards with out even informing us. Now it’s 2021 and I’m now owing over R10000 I am struggling financially and I cannot even apply for a loan because Vodacom has blocked from taking any loans. I was contacted about a week ago by Vodacom lawyers stated that I had to pay the R10000

I am in need of some serious help. Please help
