Be careful to Upgrade

I have been a prepaid MTN customer for many years, this morning I wanted to access the app to look at my balances and was prompted to install the new app. Diligently I deleted the old app and attempted to install the new app nut was refuse as this is not available for my device. The call centre advised me to reinstall the old app, which is not available any longer, the local MTN shop at Key West mall says it is unfortunate but nothing can be done. So be warned to not follow prompts for upgrading your MTN App.
