I'm not a Sky customer. So why are they calling me?

[Reader30s]

I just received a call from the legitimate Sky number (ending -372) asking if they were speaking to [my name]. They then stated I wasn't currently with them for broadband or TV and what my current provider was. I hung up. 

I've never had a Sky broadband, TV or phone from Sky. Why on Earth are they cold calling me? Is this a legitimate business practice of theirs or was their number spoofed by scammers?

I'm not aware that Sky cold call non-customers, so I'd suspect the latter.

I'm not a customer either, never have been and they've been cold calling me the last few weeks, which is how I've ended up here. 

The number ends in 3372 which in their help section, they say is their official number and NOT a scam call, so I'm still unsure why this is happening.

@yenastyyy spoofing the telephone number to make it appear that the it's genuine is a trick frequently used by scammers.
