Microsoft Xbox Live Billing Dispute Phone Number

Microsoft Xbox Live Deceptive Billing Practices

(Donnasteeley09) 'MICROSOFT *XBOX LIVE BILL.XBOX.COM WA
there was there charges 9.99 three times plus 4.99 4 times in febuary on my credit card no phone number to call so i half to dispute it through the bank'
Same thing with me except been going on for 2 years and my daughter signed up at a preteen without my knowledge. Since we have a different phone number they give us the following message before allowing us access to remove my billing account information (my daughter hasn't used Microsoft Xbox Live for the 2 years & could careless if her account is closed):
(Again, when we try to do something either through 'Manage Payment Options' or 'Cancel Auto Payment' we get the below message each time when trying to cancel for the last 24 months; I'm fighting thyroid cancer which has metastasized & I'm sure Microsoft is enjoying my lack of energy so they can keep taking advantage of me as a single mom who is critically ill)
'You recently updated your security info
We have a waiting period for the updates to take effect. On 9/27/2013, we'll delete your old security info:
‎(***) ***-**95'
Why can't they have other security measures beside a telephone like every other company in the world?
If anyone knows their Email Billing Address and/or their Customer Support Telephone # I would greatly appreciate it. You have no idea how much. I can't believe Microsoft is getting away with this. I've always been loyal to them.time for Apple.
THANK YOU!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
