Pillar to post (excuses)

I'm writing this report as I feel like Dial Direct (VAP) is trying every possible excuse. July 2023, I took an extended warranty policy, as I was buying a used car. This policy was replacing the one I had on the car that I was selling. In Sept 2023 when my car started having mechanical problems, which OEM quouted more than the price of the car, to fix them, I decided to get rid of the car. As usual, I called Dial Direct to cancel the policy and take another one, for the car I was getting next. After the call, I followed up with a cancellation email, to the email address that my policy said I must use if I need to discuss my policy. Everything went 'ok' after that, as I received new policy documents and new premiums started on my account. In Mar 2024, I noticed on my bank statement that I had 2 deductions for warranty policy. I called Dial Direct and told them. They said that I didn't cancel the policy in Sept. They told me to send the email that I sent to cancel. I sent it but they went silent after that. I called them again end Apr to follow up. I was told that my request for refund has been rejected as I didn't cancel, and there was no communication for this. I told them that I have forwarded the email proof that I cancelled. I was told that I used wrong email address and I should have used their gmail email address, of which I've never heard or seen on my policy documents. I was advised to send my claim to VAP refunds email address, which I did last week. 3 days later, they rep**** asking me to send proof that I sold the car, of which I sent within few minutes of receiving that email. In order to ensure that excuse of wrong email address was eliminated, it was sent to all 3 email addresses that I have for Dial Direct. Today, I've just received another reply saying that they can't open the pdf proof of sale that I sent. I've just resent it and I hope there won't be any further excuse.
