Customer bullying by online customer agents

Hi Vodacom Seriously your customer service really sucks and bully people a lot. I reached you on Twitter to cancel my contract as it is coming to an end on the 11th November 2020. They question they asked me are really totally unacceptable since I’m on an laptop+data contract. I’m really gatvol please CANCEL my contract. How can you ask me when last I recharge while I already told you that I don’t recharge it I only get my 5GB per month. I even screenshot my current data balance together with my current bill amount and they are telling me that they can’t help me because the information I provided is incorrect.
