Not sure if it's a coincidence or not, but after missing a call from this number, I received a text from 'Fastway couriers' with a link to reschedule a delivery. I tried calling the mobile back and there was no answer, so I hung up - and then immediately received another text from 'Fastway Couriers' with the same information to reschedule delivery.
I have not ordered or bought anything though and am not expecting a delivery, so I am highly suspicious.

I called back number 0488 923 198 reached voice mail but did not say for what company.
