Vodacom online

I app**** for a contract online with vodacom.Got sent the incorrect device. Called to have it collected.Stupid agent activated the sim and I get told that the contract was cancelled but I still have a debit order that runs on a monthly basis.I have never used the device and I don't have the sim. Promised a call back till today I am waiting. I am not paying for something I don't have and Vodacom is going to **** up my credit score due to incompetence. You guys are playing with people's lives and I don't think the company should be hiring agents that are only chasing commission and not considering the customer.
