I pay 250 rial every month and my limit is I think 2000 QR. I always pay like 200 QR or 150 QR online but the remaining 50/ 100 QR still their. after 3 months they disconnect my connection even my remaining balance is less than 300 QR and they said I still have a balance amount from my 3 months back bill. So the 2000 QR limit is no use.
