Disregard of consumer rights and abusing customers

Would Vodacom please stop victimising and abusing their disadvantaged customers with their airtime and data. My mother terminated her Vodacom contract with you last year after 2 years of your company *****ing from her account and forcing her into an airtime contract with you even after her contract had expired in 2019. This week your company continues to take from her the airtime and data which she’s buying from her pocket. My mother is ill and is living with my disabled brother. They both use Vodacom and need to have airtime/data so they can call for help at anytime there is an emergency. I cannot understand why you disregard consumer rights and abuse customers continuously. The service from Vodacom has been an absolute nightmare and this matter needs to be resolved urgently!! You should be ashamed of yourselves!!
