We have been getting a number of cold calls (at least 3 a week) from a computer software company I think based in Luton UK. Their operators all have an Indian accents. They ask if we operate Microsoft systems and tell me that Microsoft have been inundated with error messages sent, it seems from my computer. The first time they called I thought they were Microsoft and entered into a dialogue and they indicated , by linking to my computer, a large amount of error messages. They wanted me to sign up for their clean up programme and wanted me to pay £70 a year to have this done. When they ring now I ask for their telephone number and ask how they got my number, both questions they side step and their diction is so bad I cannot work out the name of the company. The will only say do you operate Microsoft systems and eventually hang up when I badger them for more info. I am not so much worried about the company as I can just put the phone down but I am concerned if there is a fault in my system and it should be corrected. Any ideas?
