Wrong Reg number on insurance Cert

[S6 ROR]

Just purchased another car on Thursday and arranged the insurance over the phone.
Have received the docs this morning, and checked them through, they have the incorrect registration number quoted, they have put PR04 instead of RR04.
Tried to call them this morning, but the office is shut as they don't open on weekends.
Does this mean that I am not insured?
What would be the position if I got stopped?
Is it best not to use the car until I can get hold of them and get it changed.
I really wanted to use it to take to a show over the weekend, but not sure whether I would be covered and legal.

Any advice would be much appreciated.

Send them an email as a written record of their clerical error now & sort it Monday when the office is open. MSM?

Hi Andy, it's Mannings.
Have brought the Halycon Midas pearl Tamora from Bespoke this week
It's a factory Red Rose and the Number plate is RR04 but they have put PR04 on the Cert.
I really want to take it to the tvrcc event at Blemheim palace this weekend, but not sure whether to risk it or not now.
