Keep taking money after account cancelled

I took out a 24 month contract for a tablet for my son.<br> <br> I explicitly told the agent that I do not want any extras.<br> They have take a small extra charge every month over the 24 months.<br> I am not worried about this.<br> <br> The contract ended last month.<br> <br> Then this month I got a debit on 2 Nov 2015 of more than the original amount. <br> <br> We have not used the account for about a year.<br> They should be able to see this.<br> <br> The next day I went and did the paperwork to cancel the account. 3 Nov 2015<br> They can not give me a copy of my contract, that states that the account carries on after the 24 months on a month to month. Which I specifically asked should not.<br> <br> Yesterday they took the same amount of money of my bank account again.<br> This is now in the middle of the month and the second time this month that they are charging me.<br> Always went of on the second of the month<br> <br> This is firstly ***** and secondly theft. As they have charged me twice in one month for something I did not sign for, nor used and have cancelled.<br> <br> I have asked for a full refund.<br> That has now been charged twice this month 2 x R183.96<br> <br> I would also like to lay a charge with the police.<br> <br> I have mailed the branch
