Policy error and refund

In February I took out a policy for my brand new car with outsurance. After few days I got another quote with another company and wanted to cancel the comprehensive cover I took. After speaking to a senior advisor, she reviewed my policy and also picked up an error that was made when I took out the policy. The cove was for agricultural use rather than the normal cover. I was happy with the cover she offered me and decided to sty on board. An amount of 1371.99 was deducted on my account on the 25 of February. When I spoke to the senior consultant she told m I am due for a refund for the money that was deducted and it will be available on the 27th of February. Till today I have not received my refund. When I called outsurance I was told the senior consultant who delt with my case is not in yet. When she comes in she will call me and she has not called me yet.
