Bad Service, Do not return parts

On the 24th of February 2015 Van Biljoens collected my Samsung washing machine. They promised to repair it within 5 working days. After 5 working days I contacted then and they could not provide me with a quotation. After 3 weeks I asked them to return my washing machine because I haven't received a quotation yet. The next day I phoned again to ask that it should be turned. On the 3rd day I was given a quotation (which I no longer wanted). I paid R150 and told Suzette that I will pay the outstanding amount as soon as the washing machine were returned. She insisted that I pay the rest. I comp****. The washing machine were returned without the drain filter cover. I phoned 7 times, I have sent a photo to show what cover is missing and I have emailed Suzette 3 times. I still have not received the cover.
