Vitality error on app

Hi

On 27 February I raised a complaint re my app not working and giving error messages. I was then told that the wrong error was logged and they would log and escalate my error. I received an email informing that the fault had been corrected to which i responded about 3 times already that the problem still persists. I am not getting rewards, I am not getting any kind of response and think the level of service is just completely unaceptable.
