Or it could be another "Prestige". The fact that none have the 0844 557 0126 phone number is of no concern because these companies often have different phone numbers for the same thing.
They advertise different numbers in different places and they can then look and see how many calls have come through each number. This allows them to work out how effective their advertising has been.
This list of three possibilities shows why more information is required.
If you are looking at buying the insurance, then I would give them a miss if they don't publish their address in the advert.
Would you put your money into a bank that won't give you its address?
