Need to pay dewa bill but bank apps doesn't work.

Since Monday FAB mobile app stopped working. I don't receive SMS alerts for transactions too. Online banking portal doesn't load. Tonight I tried to pay my dewa bill but in the last step I received an error that the payment failed. I don't know if the amount was deducted from my card but there was an error in confirming it with dewa systems or it was not deducted from account at all (which is fine in this case). I don't know because I don't receive any SMS notifications and I don't know what is my balance. I'm a little concerned because this has happened to me before with apple pay and du bills. So I'm thinking to not pay it and wait until the services are back online again maybe even next month. But will Dewa disconnect electricity and water if I don't pay it until next month?

I know there are channels to pay but as I said I don't want to pay twice. I don't remember if the payment page was asking me for an OTP code before because if it were I can be sure that the payment was not successful because I couldn't enter an OTP.
