Sham of a business stay away

Absolute Sham of a business. Please save the stress and stay away from this company. I ordered some bricks on 25 June. First they accepted order saying all is in stock. later sent wrong bricks which i refused to acecept as it will be a mismatch for my project. Now they are saying the bricks i ordered are not in stock and they are making the bricks . Since They are not able to confirm when they can deliver the correct bricks, I decided to cancel the order. I have been chasing them for a Refund now. No response on email or phone. The lady on the phone just says manager is out of office , Owner is out of country. I even went to the Pretoria address mentioned on the website. There is an old Home on that address. No signs of Clayville bricks.
