Ring then hang up quickly. Obviously wanting me to ring and take the cost of them selling me their products based on the above.

Call centre. When answering, the typical long pause in computer connections, prior to the person speaking. Lot's of time to simply hang up on them.

They ring early afternoon or around 4pm. No message.

Annoying. Keep calling. Selling some solar panels or something. Bad line, thick accent, decided to block.

4 calls this week. No message left and call back doesn't work. Very annoying, typical call-centre ?

Number keeps calling. No message.typical spam.

The number calls my mobile. I try to call back & number is "switched off or unavailable". Don't know who they are or what they want.

5 calls today.
Decided to put on block list.
They claim to represent ABC Gutters

The number calls my mobile. I try to call back & number is "switched off or unavailable". Don't know who they are or what they want. Annoying and creepy.
