con agents

i was constantly running out of data and went into a store for help. i was regularly sold more data, as well as an early upgrade and a ****le. i was only told that i would continue to pay for the old cell after i had signed the new contract, but he said just for a few months. When my bill reached R3000 plus my son called and put a cap on the data and stopped the regular upgrading of apps. This gave me a set bill of just over R1900 per month. No one at Vodacom bothered to do this, they just saw a pensioner who they could con into a sale. i feel that Vodacom must cancel the charges for the ****le and old cell as they were sold under false pretenses. i approached the manager who, slouched in a chair, only uttered the words \ you signed for it". i have spent hours on the phone and visits to try and get some help but to no avail. I sent an email yesterday but the only response i got was \"" thank you for your email"
