incorrect debit

I took a funeral cover in Feb 2015 and requested that I be debited on the 1st of every month. My 1st debit was on the 27 of Feb as the 1 of March was on Sunday which I totally understood. Next thing I realise I was debited again on the 22 March. This is unacceptable! If this company cannot stick to the arrangement then I want this policy cancelled, I would rather go to a company that honors agreements, how do I trust that you will honour the agreement should the unforseen happen .I WANT MY REFUND NOW!!!<br> <br> I have not even received my policy documents.....This is disgusting!!!!
