Bad service by Ellies installers

After waiting for a week for my dstv to get installed i am just fed up. After buying the decoder with installation at OK Furniture a week ago i was told that it will be installed within 2 days max. 7 days later still no installation. The installer (Ricardo Van Wyk) never even contacted me to arrange a date for installation. I had to contact him numerous times until till he told me that he received stock and that he will do the the installation today (after a week) at 17:00. Cancelled all my appointments for absolutely nothing. He didn't even have the decency to notify me. Is this just the type of service standard that you guys set for yourself because it is really pathetic.
