Bad services from Saint gobain and Al's hardware

Yet another complaint for Al's hardware and SAINT GOBAIN Bought tiles,cement,bonding liquid @Al's hardware.started tilling and 3 days after tilling I had to remove the tiles because there was something wrong with the cement..tillers told me the cement was fake..I had to buy the material again this time @ tile africa and the very same day the tiles were set(cement was dry(.I went back to Al's hardware from a refund..they told me they won't refund me.. They logged a complaint to the cement manufacturer (saint gobain)..they sent out a consultant and he took samples of the cement for testing..2 weeks later stil don't have the test results..the consultant wasn't very helpful..I had to phone him..he did not phne me to keep me updated..poor services..2days ago he said they wil have the results on Friday witch is today and stil no results and the consultant is quite again no response from him..bad bad service from Thabang mokoena (consultant )and saint gobain. I have been treated like a begger and not a paying customers whose lost so much money because saint gobain sold faultu/fake cement
