Unacceptable

We received a quote from Hishaam on the 3rd February for 14 boxes of Parisi Grey tiles, as we brought with our measurements and asked him to work out how many boxes we required. Upon receiving the 1st quote and discussing it with my husband we asked Hishaam to add another 10 boxes to the 14 boxes on this quote, then we received a 2nd quote from him whereby we continued to the cashier and paid for the 24 boxes of tiles, the adhesives and tile grouting. John informed us that he will be putting the 24 boxes of Parisi grey tiles at the back since we only going to pick it up over the weekend. When my husband went to collect all our goodies this morning he received only 10 boxes, the adhesives and tile grouting. He questioned why only 10 boxes as we ordered and paid for 24 boxes as per Hishaam and John that assisted us. Hishaam told my husband he knows we asked for him for 24 boxes and went to see via his computer as to what went wrong. He informed my husband about 2 quotes and 1 quote stating 14 boxes and 1 quote stating 10 boxes and that we didn't pay for them etc yet before we proceeded to the cashier I asked him to add the 10 extra boxes and he gave me the new quote for 24 boxes, thus his story doesn't add up that he gave my husband today. When I called him today he personally told me yes I asked for 24 boxes and he did give it to us via that 2nd quote. Then he became argumentative stating but its 10 boxes amounting to m2 etc that I still don't understand, thus I asked him I want to speak to his manager whereby he informed me its Dawood. When I spoke to Mr Dawood he himself was puzzled and confused as to what had transpired, after a few back & forths we started making headway. Hishaam was called in by Mr Dawood and I clearly heard how Mr Dawood informed he that he was suppose to tell us that its not 24 boxes but per m2 etc, as this was the question I asked Mr Dawood prior to Hishaam being called into his office. I could hear how Hishaam could not answer him and was caught up in his web of lies. I also told Hishaam that I'm livid in his pathetic service and now his requesting that we come to the store to sort out his mess, I told him his not reimbursing me for our petrol, our time and also money for hiring a bakkie to collect our goodies this morning. I called him later informing him that we will be canceling this deal, but not until I expose this unjustly act of what transpired.
