Bad service and stinky attitude from consultants.

Am very much disappointed on the service received during the claim process from IUA business solutions. My claim was approved the car is fixed it is just a struggle to get the payment done. Invoice sent for payment yesterday no communication whatsoever that there's anything wrong with the invoice until I called to find out, they only tell me reasons they can't pay when I ask when the dealer sends the invoice they mention nothing that can delay them making payment until I ask. The consultant has guts to tell me the invoice was sent late when it was sent the day before and they didn't say anything on receipt of the invoice first thing they say when asked about payment is"the dealer hasn't sent the invoice" lies am so frustrated would never recommend this to anyone I am very angry and frustrated.
