Customer Complaint

I took a home wifi on contract with Vodacom on the 4th of June 2025 via customer call centre,everything went well and the wifi was delivered,the agreement we had is that my debit order is on the 25th,I gave them all my information regarding debit order,The wifi was connecting fine until yesterday when I call them they tell me that I didn't pay for 60 days,I was surprised because the agreement we had is that on their side they will take money on the 25th.So now I have to pay for 3 months because they fail to deduct and that is not my problem. Yesterday I called them and they said I was supposed to go and pay at the store or bank which is new to me because that was not our contract agreement.Today I went to FNB to make that payment but the account number that I was given doesn't exist.Vodacom is very bad with customer service and I will cancel my contract with them after payment I'm done.
