Received a couple of calls on my mobile within just four days, both ringing in after five o'clock. I don't recognise the number, so I've chosen not to pick up.

I’ve had this number ring me twice in just four days. Can they not take a hint and let me be?

It seems like I've received an unsolicited call from a sports apparel provider named Zapkam. They probably scour the internet and various directories to fish for contact details linked to football or sports clubs, only to ring up with the intention of peddling their wares.

I received a call from this number earlier, but when I attempted to return it, I just got a busy tone. Can anyone shed light on whose number this might be?

Received a call, but they hung up without leaving a voicemail.
