Incorrect ID number on policy

I purchased a car in March 2019, and took out Discovery Insure. The team were helpful, and answered all my strange questions.

When I received the policy documents, and read them, I noticed that my ID number on the policy was not correct, even though I had provided the correct ID number over the phone.

I raised a query in March 2019, and notified Discovery Insure that my ID number was not correct, and asked them to update this, and resend me a copy of the amended policy or my records.

The response received on 30 March 2019 confirmed that "We have referred your query to our Data Integrity Department. The ID Number will be updated with 3 to 5 working days."

I followed up with an email on 11 April 2019, and this email was subsequently ignored, as I didn't receive a response. I then followed up again on 5 August 2019 (Life happened in between), and this time the response was that they sent me a copy of the policy.

The policy still showed the incorrect ID number.

I feel that this simple amendment is taking so long, and unacceptable! If I were to claim, I am almost certain that this would be used against me! In addition, if I had provided any incorrect information to Discovery Insure, they would most certainly treat the policy as null and void.

All I ask, is that the policy is amended and resubmitted to me by the end of the week.
