waste of time

i logged a complaint last week about autopage upgrading my contract with out my consent ,they did change my package back to my old package but only for a few days i called in to find out if all was in order and i was advised that a was being over charged for data bundle i had on my contact i was paying R50 for 500 mb n now they charged me R99 for 500 mb data i tryed to sort that out with customer care but that didnt help ,They wanted me to provide my contract showing i was to pay R50 for the data i dont have that documents and advised them they can pick it up on my bill but they still dont care as to what i was saying and keep insisting on the contract. now i am back because autopage as migrated my package back to a top with out my consent .Im really tired of this now im so disgusted with autopage i will never upgrade or deal with them again .While all off this is going on i will have to pay partial charges on my bill for they incompetence ,Please can some contact me to sort this out i wont stop here if this problem is not rectified as it is not my fault .
