I have received four calls in the UK 26 May 2014 from the number your caller quoted you 1-855-234-8747. As with you, the caller asked me to open up my computer as he had received error messages and it needed fixing. I have received other calls like that but never had someone speak so insistently before. I was polite the first time and said I did not need help but would check it out myself. He called me back immediately saying "Why did you put the phone down?" as if I had personally insulted him! After I put the phone down again he immediately called 2 more times, these times I did not answer. I think it is very intrusive and wish these people could be stopped.
Person calls and tells you that your computer has been hacked and then wants remote access to it.
The Company is supposed to be called: Computer Phone Health..
Person also gets rude and irate when you challenge him.. Does not like for you to tell him
what part of his body he can insert his phone....
Now how would he know unless he was the one who hacked it..
Called insisting they were calling from Microsoft Support Centre, said they were getting numerous reports about malware on my computer - I repeatedly asked them to prove they were Microsoft - they had an answer for everything. They used the name "Ask Remote Xperts" from UK. There is a Canada number which is just an answering service. I called and said I wanted to report that their telemarketers were saying they were calling from Microsoft - surprise - no one has called me back.
Update - did hear from Ask Remote Xperts - they are legitimate service - said they are having trouble with a call centre in India and they are working on matter.
