Tymebank app errors and lack of support

This relates to the Tymebank app; all was fine for many months and then suddenly an error E0001 started and could not sign in. Contacted the support desk who simply stated that the update had to be app**** which did not work, same error. Tried numerous times thereafter to correct the error and contacting the support desk and even uninstalled and reinstalled etc etc but to no avail, same error on login. What really then blows my mind is receiving an email on the 7th May which states "we will give you feedback on or before the 4th May" ? and then another email stating "your call has been resolved/remediated" with no follow with me to ensure all is working, which it still is not. Many of these support desks get measured by managed on number of outstanding calls and the age of the calls and therefore they close them despite them not being resolved and quite happy if you log another call as it does impact their measurement criteria with management.
