Table top delivered chipped THREE times, still no refund 4 months later

We ordered a table with a glass top from Coricraft Mall of Africa. It was delivered mid September. When the installers unwrapped it, we found that it was chipped. Coricraft kindly offered to exchange it. A couple of weeks later, a second table top was delivered. It was also chipped too when the delivery guys unwrapped it. By that time, we were already greatly inconvenienced. A third table top was ordered. But of course, it was also delivered chipped upon unwrapping! We were growing so tired of such incompetence that forced me to stay at home to receive table tops (incurring money loss for not doing business), and owning a expensive new piece of furniture that was not perfect, that we decided to not replace it, but demanded a gesture from Coricraft instead for all our troubles and disappointment. After several exchanges that led nowhere, a partial refund (partial only, because Coricraft clearly does not value our customs that much to refund us fully) was granted. We completed the form at Mall of Africa, in November. To date, I have had to chase Coricraft 6 times to get an update on this partial refund, which has still not been given us. We have been promised calls and emails from management by the employee dealing with our case, but nothing. To sum up: Coricraft goods are flawed (at 8k for a table, you'd expect perfection and quality!), and their customer service, despite answering readily by email, leads to no resolution whatsoever. We are extremely disappointed by Coricraft's carelessness. We are now the owners of an expensive piece of chipped glass.
