01233 Scam and Survey Calls: Who is Calling?

I am receiving several calls a day for the past week from 01233 telephone numbers with automated messages about Amazon account and internet connection being hacked. I just put the phone down. The caller had an Indian accent. I know that although some of the calls are scams, I have received calls from Facts International at a 01233 telephone number asking me to do a survey. When I did my research I found out my Bank gave them my number. If you have received calls from 01233 numbers, please share your experience by leaving a comment below.
