Poor service.

We were charged for 4 pairs of 3D glasses instead of 3. Admittedly did not check the receipt until we were given 4 sets for only 3 of us. When we explained what had happened were told point blankly that there are no refunds. Perhaps this was an honest mistake, but what if this is a ****. Either way I would expect more.. I wonder how many other people this has happened to? I will not be attending a Ster-Kinekor again
