Appalling customer service by *********** staff

I have contacted the claims department querying the inconsistency of the Mobile App and the website, today when I make a follow up I get told that they cannot trace any interaction with your contact centre. I would like to submit my claim using the App and I expect someone to do their job and resolve this issue I have with the login process. I can login on the website, and not on the app. How pathetic is that, to make matters worse I get emails encouraging me to use the app that is not functional. Really, get your act together. I have had it with people who do not understand they roles, the last lady I spoke to had the decency to tell me utterly nonsense. Please do me a favour and confirm the date of cancellation of this policy, and do not let any of the Retentions consultants contact me.
