Budget opened a new policy in my name without speaking to me

I woke up yesterday morning and received an email relating to a new policy on my name from the Budget Value Added Products Department. I was surprised about this as I have not spoken to anyone from Budget, or signed up for any new products.

After speaking to my mother in law, I found that a telesales person had called her, and then signed ME up for additional tire and dent cover.

I am confused by how Budget can simply call someone and not confirm that the person they are speaking to is the owner of the policy before adding new products to that persons account.

Background: I am paying for my mother in law's car insurance. I am living in the Netherlands. Budget does not allow for international numbers on their system (And I obviously do not have a SA number anymore), thus my mother in laws number is on my Budget profile.

Additional note: Hello peter also does not allow for international numbers. Thus the number I have input below belongs to my mother in law. She can supply my cellphone number
