Contract cancellation not activated correctly

Hi,<br> <br> I cancelled and paid the outstanding amount for contract with Virgin mobile in October 2015 as I wanted to use my current number for a new contract with MTN as Virgin mobile didn't have an affordable deal fro the new IPhone 6. I was told everything was fine, I went through to MTN and had my number ported.<br> I noticed a debit order had been taken off in December and then went back and saw had been done in November as well, I called to ask what was going on and apparently my contract had not been cancelled. The call center agent then proceeded to \cancel"my contract and assured me I would be refunded my money - I did not trust this so recalled the Debit order with my bank.<br> I was then debited again - same story"
