Very disaponted in vodacom

On 9th of May 2018 i called vodacom cancellations department to get the settlement amount for my contracts upon our conservation the lady advise that she will send the quotation which she did and there was two different amount for two different contract , she then advise that i should make payment before 14days to any vodacom shop /Absa bank .on the 11of May went to vodacom shop at centurion and pay up the whole amount which was on both invoice and the contracts were cancelled on 29 of May vodacom debited an amount R1289 which i was not informed about and if it it was any instalment amount was suppose to be R489. when i call to find out i was informed that it was a VAT amount , the gentleman was so rude he then transfer my call to legal department and i spoke to a lady by the name Dorcas she then advise that on her system she only see a total amount of R6487 which was supposed to be paid .my question is that is it my problem that you guys have different amount on the system this is very disappointing its like someone is creating their on amount is this how you do business and your consultant should learn to give the best information to those who doesn't know .If I had money why would I cancel the contract I should have left it like that and not pay you anything.I risked and took my savings to pay you up know this is what I get in return ask your self how many people are in debts and not paying you guys you are ungrateful.
