Worst service,wrong sell

I received a call last month and the consultant told me about migrating my account from R215 to R475 airtime to still pay R199,00 and I migrated the account.I have 2 accounts with them and I asked her to get a clarity that is it going to be R199 per account she said yes, I am busy getting messages from Vodacom that I owe R1000, when I call the Call centre, one of the consultants was very rude,saying she won't help me because I failed 1 security questions that I am not sure my last contract how much was it I couldn't remember whether it was R215 or R225.When I call again they refer to this Tobi of which I am not getting assisted.Ibhave been with Vodacom for more than 20yrs but their service is getting worse. My account number is I***5 Angry client
