I sent many tickets to customer support but they even didn't reply my ticket so far.
I was talking to Microsoft chat yesterday, send your ticket
first, then go to chat and wait in the queue.
You can only try, good luck.
1. I chatted with support but they said it is not their work and asked me to send ticket to Custom Support again.
2. I sent ticket with normal hotmail,they replied instantly but with msdn hotmail they never reply
That is not very nice of them at all, I got my own question sorted out in less than five minutes.
Here is my method, do not use support, chat I used
https://support.office.com/home/chat ask them to pass your query on as you are having problems with contacting support, this may be your last option.
I have two types of hotmail, online login and desktop version of outlook for the office suite.
I am not sure if it will work for you, as I am thinking you only have an online mail account.
