Unhappy customer

So I have been on Outsurance for a year now and within this year we have had 2 incidents one being our vehicle which was June this year and being provided the most exceptional service from Trivashen Perumal. He had helped us a great deal when it came to our vehicle.

Then we had a claim in July for a lost phone due to the Hassel's of trying to get it blocked and so on we then were told that we were cancelled by our previous insurance which we knew nothing about and I'm in the process of taking them up for that. The outsurance agent told me that a cancellation letter was done in march and back dated to October 2017. The reason we cancelled miway was that we didn't want a problem when it came to our vehicle our last payment to them was made In August for cover for the month of September, but long story short this is now a problem plus they sent me a document which needs to be filled by the members of our family this was explained to the other assessor we contribute to accounts but we live our separate lives now I'm expected to go up to them and ask them to provide there private details to me.

I just want someone to remove the item from the poilcy because it's seems the will not pay out any claims due to contents.
