We want our money back

My husband and I paid >R32k deposit. Prior to paying our deposit, customer service from Janine Mahabeer good. As soon as deposit paid, impossible to contact any of the staff, Robyn, Ashne, Jim. Two installation dates were cancelled on the day of installation. Despite asking numerous times for over a week for another installation date, and receiving none, we requested a refund. Our refund request was acknowledged by Robyn via email, and a date for refund given by her, however the date has come and gone and no refund. We are opening a ******** case on Monday.
