Had 3 calls from these people in 15 mins. When I asked them for the error code they are getting they say they will call me back.
Is there anything I can do to stop these calls.

This number is used by fraudsters claiming to be Microsoft. They direct you to a website where you download a remote control program so they can take control of your computer. Either to host viruses, make your computer a bot or steal your banking details. I've just spent an entertaining 2 hours, stalling them and claiming my computer crashed whenever I clicked on their download.

They even tried selling me a Microsoft Certificate (£125 for 5 years, £150 for 10 years or £175 for a lifetime) as they couldn't get their program running on my system. Unfortunately my credit card was invalid! These people can be very convincing and are very patient. Please note Microsoft would never call you out of the blue. Either play them along like I did (so they're not calling anyone else) or just tell them you don't have a computer. Hope this helps!
