Amazingly exactly the same thing happened to Granger99 and Edger in these two threads here :

“Oddly enough somebody called me on my mobile a few weeks ago and said he would give me £50 if he could not save me money on my mortgage.
I kept him talking for a bit and told him I would have the £50 as my mortgage was paid off over 20 years ago.
I am still waiting for it.”

“I had a call a few weeks ago saying I would be given £50 if they could not save me money on my mortgage.
I strung them a long a bit and then asked how they were going to save me money on my mortgage as I paid it off about 20 years ago.
I am still awaiting my £50. “

At the time they said they didn't get their money so I doubt you will unfortunately.
