Not from Sky. 2nd attempt. Offering 40% discount for 8 months on a product. Nearly fell for it. Wanted to reset password after they sent a 6 digit number. Refused to do it over the phone. Female with Asian (Indian sub continent ?) rang off. Spoke to Sky who confirmed not them. Left Sky with the number.

This phone number is a sky centre call number. I do not have sky and they could not give a reason why they called me. They were fishing for new customers.

Caller: Sky
