Zain's online system for Quickpay is the WORST. I didn't have problems with it for a while, so the past several months, I've tried them again. No more.
SO MANY of my friends have had the same problem - over and over and over and over again (going back as far as 2006!): You input all your payment information, and on the final page where it asks you to hit a "confirm" button - and you do; instead of giving you a confirmation/receipt for printing as it should/usually does - it transfers you to an error page. If you go back (as the error page suggests) and confirm a second time, your payment will be deducted a second, third or how many other times you hit the button and receive error pages.
Nice little trick Zain plays, right?
When you call their Service Center, they will ask you to call back. And call back. And call back. And they apologize (thaaaaaaaaaaaaaanks), but the problem won't be resolved for weeks. I send faxes and e-mails and call continually - no one at Zain cares. I don't even get a response to written correspondence.
If they know there is a problem with the online system, should it have taken them 2 years to resolve it?
I STRONGLY RECOMMEND THAT ANYONE WHO IS EVEN REMOTELY THINKING OF GETTING A MOBILE NUMBER IN KUWAIT - DO NOT CHOOSE ZAIN.
And - my calls have been consistently dropping lately - as have most of my friends' who use Zain.
Why do I stay with them? Because I have had my number for 11 years and I can't transfer it to another provider. If I could, I would. In a nanosecond.
