Bad service and the run around

I am an Edgar's account holder and I have been trying to lodge a claim for the phone this was in march 2021 I went to the store and they made the call to the insurer only to find that my details have not been updated since the last claim and i have been going back and fourth every time they say my details still not updated i have sent emails trying to have this problem fixed and the insurer AUI sent me an email saying they have updated the information. other other hand I took a phone in October its cost was around 3299 I paid that in 3 months but my bill does not come down and my premium for insurance to the Edgars they say I am suppose to pay 600 and some odds where AUI says 500 and some odds of which that is what is known to me I have record of the emails from AUI . this is frustrating to me as I need the insurance for my gargets and phones i have been with them for a long time and its no easy to get insurance from other stores if you bought the phones and gargets else where other wise i would leave them with immediate effect. and I cant afford not have insurance for my phones and gargets as they cost a lot . please assist.
