I took out a land line rental with Sky four years ago, it was clearly a recycled number as just googling it, I discovered it was being used by a former discount store.
Initially I was getting dozens of calls everyday, mostly spam, but also the occasional one from people enquiring about what we sold and those assuming it was a business and trying to sell services.
Registered with the TPS and asked every site I could find and Google to remove any reference to my phone number where it had been attributed to the old business.
I now get on average one call or so a week. It's always foreign call centres. Given how little I use the phone, I leave it on answer machine, so I typically just end up with messages left of beeps where the operator hasn't picked up the call yet.
