Waiting Game......Unprofessional

I have logged my insurance claim 22 July 2018. I have sent all documents by the 26 July 2018. Budget said i will get a feedback on the 1 August 2018. The 01 August came and they called to say the 14 August 2018 will be the date i get feedback. I called them on the 15 August 2018 to follow up as they did not call. Was told they will give me feedback on the 21 August. Today is the 21 August and I still get senior consultant is till busy. SAME STORY!!!! Does it take a month to validate. This excuses is frustrating and not making it easy. With other insurance companies does not take this long. Can the communication be more effective. Same update with a week difference is really unprofessional!!!!!
