Do not call 1 877-701-2611 because it appears to be a fake Microsoft Technical Support telephone number. The fake number is listed on a lot of free websites where online users are asked to call in order to contact Microsoft for technical help. But, this number is not associated with Microsoft.
One website currently asking online users to call 1 877-701-2611 is msnmembercenter.com, which is NOT Microsoft website and is not associated with MSN.

The same fake telephone number (1 877-701-2611) is also listed as technical support number for IncrediMail Tech and HP.
Here are other two fake technical support telephone numbers:
- +1-800-862-9240
- +1-855-785-2511
Online users should never give out their credit card information over the phone to make payment. And, for online users who have already contacted 1-800-862-9240 and given their credit card information, are asked to contact their banks for help, to stop the fake website from continuously making fraudulent charges to their credit cards. The bank should be able to cancel the transactions or charges and refund their money.
