Calls started at 8:30 a.m. Have had 7 today and it's 1:45pm. I did return the call to be told by man with thick foreign accent my windows had picked up a bug that could destroy my computer. I told him I did not own a computer and he hung up without comment. Then I got 2 more calls from them. They used multiple phone numbers, included unknown.
This # called my mobile, left no message. Has same first six digits as my mobile.
Caller Id read EBay. Doubtful.
