Non payment of use of accommodation

Hi there<br> <br> On the 18th of January a company called Elgin Engineering made use of my holiday accommodation in Skiathos Bay Langebaan for Chinese technicians of theirs working in the area. Their stay was from the 18 Jan'15 to the 23rd Jan'15. The total cost was R1,750 for the week. I until today not received payment. I called them and they promise to return my call but still not contact from them. I also sent them emails and not response there as well.<br> <br> Their contact detail is ***<br> <br> Please can you assist me in getting into contact with this company in order for them to make payment for use of my holiday accommodation.<br> <br> Thanks<br> Michelle Bergsma<br>
