dissapointed

My contract is about 20 months old. Never have I used data because we have uncapped data. My kids unticked the wifi option and we received a bill of almost R3000. I was shocked but have realized that it was my mistake. I went to Vodacom Tzaneen to literally BEG them to help met with down payment. They said I must phone customer care. I did that, TWICE. Asking them to pay R600 per month. Received a reference number: S3-8DH2R-R0T88. I received a sms that I will be contacted within 2 working days. I wasn't contacted. I phoned again, the consultant said I must pay R650 a month. I agreed. Well, my debit order went of for the total amount! Needless to say, my house bond didn't go through. Thank you for nothing Vodacom. I was more than prepared to pay every last cent. I just BEGGED you to help me out with a downpayment. I feel nothing for us. Please cancel my contract from end of November when it expires. I will NOT upgrade. I am DONE! Cell number ***. Regards, Mr Jansen van Rensburg
