I dont work for QTEL....YOU could call their customer service to find out why?

If you hated QTEL that much for what happened, close your POST PAID ACCOUNT and switch to VODAFONE.

Or get a VODAFONE SIM (like everyone else is doing/done).

I both have QTEL AND VODAFONE phones so I dont have a problem. I suggest you do the same...less frustration for you in the future.
