Greenlight Policy (Terrible Service)

I have an Old Mutual Greenlight Policy ( *** ) that I have had since 2010 that I am not even aware of what the cover amount is at this stage. I have made countless phone calls to the contact centre in this year alone for them to just tell me what I'm covered for and its always the same thing - my profile shows up however no cover amounts reflect. I'm put on hold for over 20 minutes each time while they "investigate" the matter and always come back to me stating that they would escalate the matter. When I ask for a reference, they state that it will be sent via sms and it's never received EVERY SINGLE TIME. I have realized that all these agents I've spoken to truly don't know how to deal with my situation and as a result would avoid it completely, even after they promise to get back to me with feedback. I cannot pay a monthly fee for such a long time not knowing where my policy stands. This is ******** and warrants legal action.

Furthermore, I don't want to be advised to log in the app when the app itself has zero information such as cover amounts and latest policy schedules (which I have not received in years)

I need to be contacted urgently with clear amd concise information because if something happens (God forbid), I don't want any hassles.
