Claim just left in the air, wasting time and not being considerate to customer

Logged claim Monday 13 Jan, contractor came out 14 Jan and then contractor asked bank to send assessor. today is 21 Jan and everyday the person answering the call just says the assessor will call you today or tomorrow. No one follows up or pushes the assessors to just do their jobs and call the client? There is no accountability within this organization. I have just now tried to call to cancel the policy with a senior person and after 6 minutes no answer. Large companies like this are always reactive and not proactive, if the people appointed just do what they suppose to do us the clients wont need to communicate to you through this platform.
