inSure Poor Service - 3 Weeks later no response on insurance application

I app**** for insurance for my iPhone device since the 3rd June 2022 , and been calling in to follow up on status and finally received a revert on the 8th June 2022 with request of additional documents which I immediately responded with. I have sent a follow up email on the 17th June 2022 and till this day I have not received any feedback or acknowledgment of the mail. Its almost 3 weeks and I still have no indication that my device is insured or not. This is terrible and unprofessional service from inSure. This actually leaves one with unsettling feeling and dread the day one has to claim anything from the insurance because it does not seem like any assistance will be provided if the application process is this appalling.
