CAPITEC APP WOES

I am an Capitec account holder and client. I keep on getting emails and msg's stating that i can renew my vehicle licences on the Capitec App. Despite trying to do that weekly for the past 2 mths, i keep on getting a message that there is a problem and the developer is aware thereof and will fix it. I have contacted the developer and entered into email correspondence for a while and was told all is fixed and will work . Despite this i keep on getting the same message and cannot renew my licences. The vehicle licences to be renewed is visible on the app but no further transaction is possible. I also went to my local Capitec branch at Mall@Reds today and despite the assisting lady's best efforts, the problem remains unresolved with the developer. It took the app /developer staff almost 20 minutes to answer the call from the Capitec Branch. Only the same promises as always- try in 24hours again like the last time. What will change in 24 Hours on my APP that cannot be rectified immediately ? Terrible backing and empty promises from the APP which should not have this functionality being distributed and communicated anywhere before it actually works.
