Outrageous!!! I am blocked without any warning in advance!!!

ZHI-MENG W.

This is my child's account. I am talking in this account because my own account is blocked.
I received a wired email this afternoon, and at the same time, my account is blocked. I cannot make phone calls, and cannot logon the web site. This is no notice in advance.
Here is the email:
Bonjour,

Hello,

Yes, it's a prepaid phone plan, so when the payment doesn't go through, the phone will stop working. Contact customer service to try and fix whatever the problem was with your card.

There is absolutely no warning/notice IN ADVANCE. The blocked my phone AND web access all of a sudden.
This is no instruction of how to resolve the problem.
The only channel left is facebook, which does not help at all. They keep saying let me wait while another team is doing the investigation. They don't give me contact to that team, and that team does not contact me either.
I double checked with my bank and my online bank transaction. All payments are done normally. There is no rejection. It's totally Fizz's billing system error.

my account is blocked?
what is that?
I cannot make any phone call now
what's happening?
I never changed my credit card information, and that credit card worked before, and it is still valid, nothing changed, should still working
I cannot logon, cannot send/receive phone call

thanks
Even if the transaction failed for whatever reason, my payment period start at 19th
So for this month, I already paid, you shouldn't block me
Even if everything failed, you should notice me and give some time to fix the problem. You cannot cut me out without any notice in advance
Can you please unblock me right now, and we figure out the problem following
Thanks

Fizz: 3:19pm:
We are sorry for this inconvenience. As you previous were informed your account was blocked after an investigation which showed that the payment transaction has been rejected by your bank. This is why we advise you to check with your bank.
I am really sorry but i don't have the means to reactivate your line right now. I can assure you that your situation is being analysed by our financial department and they will contact you to do the verification before your account can be unblocked.I will kindly advise you to have in handy the following documents: a copy of your identity card, a bill where the service address is visible and the last 4 digits of the credit card.
Thank you very much for your understanding.
Have a great day!
