I got a missed call to my mobile phone from this number at 17.40, Monday 8th June, which I didn't hear. When I called them back between 19.45 and 19.55, a man answered and said hello, but when I asked who he was because I didn't recognise the number, he went silent on me, not responding to several questions re why he had called my number. I also noticed that I had had another missed call at 14.30 from 020 3838 9027 (very similar number) and when I called this number back twice for the same reason, right before I called the above number, I got the same man answering and again going silent when I tried to ascertain the reason for his call. It was me who hung up for both numbers.

Missed the call so I called them back 5 minutes after, no response from them after they answered and they hung up after a few seconds of silence.
