No Feedback from Total Loss departments

Why does innovation group not provide feedback? I registered a claim and had to wait a week for them to uplift the car(fair enough), then I eventually got told the car is written off after i called to ask. This is where the frustration starts, after completing all forms, I got told that they never received the documents. More days passed, I called them +- 10times(spending an insane amount on airtime because you get transfered up and down and authenticated) just to find out that my documents are now in their spam folder. Eventually I get a mail with a settlement offer that i signed and returned on Wednesday evening, again dead silence from this company. 3 mails sent to "Vapsinvoices" and no reply, not even acknowledgement on receipt of mail.

All I want to know is did you get my mail(signed agreement, when will the payment be done? Do you have my banking details to pay the claim to?Again feedback please!!!)

I Wouldn't be surprised if you dont reply. This whole process has been a total nightmare from start of claim to now.
