Its Hamper King

This number I dialled back from a landline... and music played for about 20 seconds, so I hung up

I got a call from this number and I dont know who it is, no message left

I have received a few calls from this number at work. When i answer they hang up, so i called back today & they just advised that they called me in error

If it is Hamper King, I wish they would pee off as I get at least 3 calls a day from that number and have never even been a customer of theirs.

It's Hamper King, I just rang and checked.  Do you have an order with them?
