Selling device on false promises

Telecom Company phoned me to sell a telkom mobile contract with the promise of 10GB wifi data available. I took two contracts and asked if I will be able to use this Wifi in the Northern Cape. They said I can. I couldn't. Tried cancelling the contracts even drove ****m to the closest telkom shop as I was instructed to do by telkom. They said they will investigate and contracts will be cancelled. I am still paying for this service, for this service that I cannot use. When i try to get hold of accounts its always a bucket pass excercise to get this cancelled and it never ever gets finalised!!! Very very very poor customer relations and service. This is not my first tedious exercise with Telkom. They are easy to get hold of when you want to buy something, but when you need after sales service you cant get things sorted at all. I will recommend any ISP other than Telkom.
