Hello everyone. Recently (9 Jun) i bought myself car insurance from Sky insurance, who insured me with Markerstudy group. On Wednesday(15 Jun) I received letter saying my insurance has been voided due to "details used to take out this policy match against multiple policies which have already been cancelled or voided by us due to suspicious activity". I thought its some sort of mistake since I am a learner driver and it was my first car insurance. Today(17 Jun) after couple phone calls I managed to obtain information that the policy was voided because my mother who was named driver on the policy had previously had her policy cancelled which i didn't disclosed when adding her as a named driver. This was surprising for me as I took all her details from her current insurance confirmation which states that she never had any insurance voided or cancelled. after finding and going through all the past insurance paperwork, I found out that in July 2014, IGO4 had cancelled her insurance because she failed to provide them with scans of her driving licence, which had to be done through some form on their website. My mum claims that she uploaded images twice( after buying the insurance, and after receiving letter about missing documents) through the website they provided, apparently it was some system error on their part and they said that this was their error and this cancellation will be removed from the databases. But since it was a phone conversation I don't have any proofs of that. my mum has policy for her car, where it states she never had any cancellations, she is named driver on my dads car, where it also states she has no cancellations, and I got my insurance cancelled because I didn't disclose information about this cancellation. This voided insurance has bumped up the prices for my insurance from about £500 to £3,500 according to gocompare, and since it is my very first car insurance, I need help as I don't even know who i should call now to try to explain this. Thanks
