Bonitas dragging their feet

I have been going back and forth with this scheme regarding my savings refund. Submitted all the documents even the ones the asked to re-submit. Called so many times and every time I have to explain one thing over and over again. My query goes to their finance and from there nothing is being done. If I call to enquire they ask for documents they after submitting still nothing gets done. It's like they want you to give up so that they don't pay what is due to me. To this day is still back and forth

We need an option to attach proof
