I am trying to use the money I already have in my account to pay for my bill but it keeps saying "An error occurred updating your profile.There was an error updating your account contact details. Please try again later" ... I'm not sure what to do I just want my phone working again .
If you had money in your account it SHOULD show as a credit and your bill would be...
(your monthly bill)- credit on your account.
So assuming you had enough credit on your account, your bill should be zero. Any excess would be carried over to your next bill as a credit. Any balance would need to be paid before they re-instate your account.
If your bill is up to date and theres no service, check you have a DD in place. They wont allow service without it.
