Cancelled Policy - money deducted twice in two days after cancellation

Due to claims taking 4 weeks to resolve, I cancelled with Virseker. I did receive several phone calls after cancellation (better service than I got when I was with them), wanting to know why. During these calls, as well as with an email it was confirmed that my membership would end at the end of March. Then an amount was taken from my account on the 30th of March and again on the 2nd of April.

Now I will have to wait in queue for 15 mins at least to try and speak to soemone before to dicuss, hoping that this will be resolved before the end of April.
