Stupid music playing, "your call is important to us, one of our team members will be with you soon".
From searches, number seems to be scam insurance?

Called and then nobody on the other end.
Has happened 6 times.

Caller: Claim to be a Motor Insurance Company

Then, when you ring back it goes straight to a door bell music, there is no introduction as to who you are calling. Scam steer clear!!
