How should I apply for refund of QR280 (I am 1 of the 1st 1000 customer)?

Should we send you an email (what is email id?) or PM on Qatar Living with our Vodafone numbers? How long will it take for the refund to be processed?

I am from 1st 1000 and still havn't moved to Flexi and dont intend to continue.

Kindly provide all details about the refunds here...

Thanks.
