How to deal with fishing letter from debt collectors

frenchtoast18

Hello,
I have received a letter from Moorcroft asking me to contact them regarding a "personal matter." There is no information on what this is, what the debt is, the company, how much etc. 
Instead, they have asked me to get in contact with them, either by phone or by entering a ref number online. I have not done this because I do not want them to have my personal data or to leave a footprint. I don't think it is fair to incriminate myself when I have no idea what it is about.
And this is the thing. I have NO idea what they are after. I am not in debt, have no debts, pay all my bills and have decent savings. My credit rating is excellent.
The only thing I can think of is I terminated a gym contract early three years ago because I moved away. I notified the gym in writing and cancelled the direct debit. Another debt company then, shortly after, were chasing me for payment, which I ignored, and they went away after a couple of months. This contact ended a good few years ago and is literally over three months left of a £30 a month gym contract. Could Moorcroft have really taken this over years later and bothering to chase?
I just wondered if anyone had experience a similar vague letter and have any advice?
Thank you

They could also be looking for someone with the same name as you, and want to eliminate you from their enquiries. No need for you to respond in any event, though I can't see it would do any great harm - what would be "incriminating" about it?

I’ve had a few debt collector letters over the years, though not addressed to me directly but to a very similar surname.  I knew it wasn’t for the previous owner and I’d lived at the address for about 15 years, so it was a ‘fishing’ exercise.  I contacted them to point out their mistake and they told me off for opening a letter not correctly addressed to me!  I didn’t hear from them again though.
