just read up on others that went thru this 44-207-444-8124 mess. most said that it was an auto dialer that says your warranty is expiring. DO NOT ANSWER these calls and they are most likely fraudulent or other wise to gather your personal information.
I've received around 5 calls from this number, claiming there is a problem with my credit card and then it goes into a sales type call for another credit card.
Just got a call from this number (207-444-8124) on my cell phone, but I missed it. A couple of days ago I also got a call on my cell from a similar number (207)435-6324. So I'm assuming they're related.
