Worst service ever vodacom

I phoned tonight again to cancell the bonus 250min on my contract. I have been phoning from October 2022. I will not pay the amount for these minutes as the operators confirmes it is cancelled. I never received an sms and I had enought of Vodacoms bad service. You need to reverse the 250min from my contract as at the 1st of February 2023. Because of your mistake you will fix it. IWILL NOT PAY FOR IT. Worst Service ever !!!!!!!!!
