Useless Discovery Insure

I was with them Discovery Insure when first started was not a great experience kept changing things on the policy. So moved to outsurance. I got a call from a broker selling Discovery Insure and tells me things have changed and it is better listened to the pitch and made the decision to go back. Not even a week back with them and they are giving me the run around. When I use the app to find out what needs to happen next I get no reply from them and sent again a query on the app nothing. Then I try the email I send two emails in two days I get an email back asking for my details. But then no answer back from them. I give them a call today the 05/03/2021 get such a run around from the lady on the phone saying the same things over and over again. Totally disregarding the fact that no one has contacted me from discovery in over a week. Keeps telling me the app does not have my details which is what the point of the app. Then I want to cancel and no one picks up the call for me to speak to holding for half an hour. Nothing has changed there they are still as bad.
