Hirsch Silverlakes - dissapointed customers

We purchased a loungesuite from hirsch silverlakes on 3 june 2018. Delivery was to take place between 6-8weeks. We are now entering 12 weeks without delivery or indication of when we will deliver the order. No feedback from the salesman or management has been made despite our request. A follow up email was sent to head office on 31st of August without any response. The loungesuite cost us more than R40 000 and we have not received any apology, support or customer service from Hirsch. We expect immediate feedback or we will cancel our order.
