Extremely buggy

Really a terrible app. Can’t even pay for bills without the app glitching.

April 2026 update doesn’t work

App was fine but the update has erased my account on iPad and iPhone. WhatsApp customer service were no help. Online account is fine.

Miffed customer

I lost the use of my app today and that is what I use to pay my electric bills, reason being that the current app has an upgrade to a specific apple version before apple have come out with the IOS version not sure what I need to do to rectify it, guess I have to wait until apple comes out with the update for my phone

No invoice available on line unless signed in first! More time wasted!

Don’t need to write a review as far to convoluted!
