Catching Out Clients with Lies

AnumberofmonthsagoMrPmobile phoned and persuaded me into a contract with them for a tablet for 24 months. Before I agreed to try it I questioned them about the availability of a signal here and whether WiFi would really work here and they assured me that they would.When I received the tablet no instructions how to set up, so waited for my daughter to visit me 10 days later to help me set everything up.We then opened package with the tablet,but when we tried to set it up,though the tablet itself worked, the SIM card didn't work and there was no signal or WiFiso the tablet was absolutely useless to me it was Saturday and offices were closed, phoned on Monday and started with my complaint,after numerous calls and emails and me specifically cancelling the contract after the first payment they are still taking the money from my account every month by way of a debit order, they are taking R29.00 more than they originally quoted.I have reversed the payment each month.They want me to pay a penalty of nearly R2000 to cancel the contract and I have refused on the grounds that they **** to me about the signal.Want to return tablet cancel contract, pay no penalty.MISREPRESENTATION!
