Telemarketing fir solar panel

I think this is a tele-marketing company but not sure. Very annoying calling and hinging up before saying anything..

have just received a call but they hang up as soon as I answer ...

Answered call from this unknown number, as I was awaiting test results from the doctor. Did not speak at first, line made a crackle of sound then hung up??

call every day, I think they just have to make calls, its just stupid, how would they get paid, and why/ how/ would they be so low to work in this industry????? sounded Australian but I just pretend to have bad line.

received call from this number today, they didn't speak when I answered. Have blocked this number..

Same here. F****g bastards

probably another Indian peasant

they keep calling my number also and hang up whenever I answer it? :|
