Poor service

I am a customer with nedbank and have my vehicles and cellphone insured with them. I have submitted all requested documents regarding a lost cellphone claim on the 6th of March 2023. It's past 10 working days and my claim is supposedly still sitting with management for approval. They are untrue to there word as a bank and misleading to there customers. I will be cancelling my insurance and want no further dealings with this bank in the future
