This company keeps bothering us with phone calls. When we answer they hang up.

Same here Wenzel.  Annoying when you get to phone and can't speak due to asmtha.  Telemarketer...poor  baby, can't understand why people hang up, especially at dinner time or whatever.  This is a scourge today instead of pestilence and plague.

Received a cal from this number today, but when they came up against our answering device, they hung up. I called the numbet back, but it was busy.

Well their customer service or sales person SUCK because they don't say a word.  We kept saying HELLO HELLO and nothing.  Irirtating to say the least.
