Claim issues

Claim logged on 21st November after heavy rain on the 20th November. The service provider came out 26th or 27th November. The claim was approved on the 29th November. We called the service provider on the 2nd Dec to confirm when the repair would be done and he said that he was having an issue with discovery cause the wrong quote was logged on our claim by the discovery claims department. We then pressurised discovery to get it rectified. An assesor came out to the property on the 3rd and it got approved for the correct amount. Today we questioned the repair on the quote i.e to ask for the cause of the leak to be fixed and not just the resultant damage. Discovery then said they will now send out another building assesor who said they will come check the roof. The service provider then said that they are assuming the water is leaking from the defects in the waterproofing. Either way the claim was approved. I dont see why they are now making excuses on the repair or getting an alternate assessor coming out. The lack of competency from the claims department, assesor and the service provider has caused a massive delay. I could have fixed the issue myself had i known there was going to be a problem. The delay by the incompetency has caused the resultant damage to worsen due to the bad weather over the week. I want the cause and resultant damage to be repaired this week. We do not have power due to the water leaking into electrical sockets. Please could you get this resolved and the damages and cause repaired by Wednesday next week. This is the festive season and we have a new baby about to be born. I have no issue with only the resultant damage being fixed but just note i will call discovery over and over again to fix the resultant damage. Alternatively i will get this logged with the ombudsman.
