NEVER, EVER answer a phone call (mobile or land line) from a number you do not recognize.  If it's important the caller will leave a message. These SCAMMER/SCUMBAGS WILL NEVER LEAVE A MESSAGE

they act as a technical support and keep calling me but I just ignore the calls.  are they scammers.

they just keep calling and I just don't answer now.  I let the answering pick it up and they don't leave any message.  I wish they stop calling me and bothering me.  they are upsetting me.

YEP,
Wanted me to give them access to computer using "Team Viewer"  they said they owed me a refund for some kind of PC Support I got from Norton Support  and that was the only way they could refund me.  They had my name, email address and cellphone number.   Idiots!
Sounded like he was from India.

My mom received a call today from this number. The caller said that he needed to discontinue service that his company was providing. He wanted her in front of her computer. She said she wasn't home and he asked when she would be. She was vague in her reply.
