Please help! Customer in distress

My name is Shevreo Petersen. My family and I decided to relocate to New Zealand in June 2022. We obtained the services of Migration and Investment New Zealand. Unfortunately, after a year, we were advised that our application was unsuccessful. Hence we requested a refund and a cancellation form was provided by the company. I forwarded the cancelation form to the company on the 26th of February 2023. Still awaiting feedback, from the company, very dissatisfied customer. Awaiting any response, from the company.
