Poor service

Join Discovery thinking they will provide professional and diligent service we updated our risk address on the 4th and 5th of December 2019 I then called in on Thursday the 2nd of Jan 2020 to register a claim for my tv. The consultant advises me the old address is pulling through but she can see we attempted to update the policy and she will ask IT to rectify their error I called back today Monday 6 Jan still nothing has been done what I can’t understand is our premium went up after the address changes on the 4th yet discovery says its still reflects as our old address ???? 3 days still no help will definitely look for other insurance cover if a Tv claim gets handled like this imagine your car.
