Customer service is dead... Don't bother with these guys...

I bought 100l of plascon paint to paint the interior of my house. The colours where mixed and I gave it to my contractors the contractors started painting and once they had finished majority of my house with an unmixed colour they had alerted me that the 2x 20l of paint that was supposed to be a certain colour where both different one was almost pure white paint. Needless to say I immediately went back to leroy merlin Boksburg to rectify this issue they gave me a 20l of the correct mix but now I faced the dilemma of having to fork out an extra day of labor at my own expense, when explaining this to the store manager he stated that he was doing me a favor by replacing the paint that was supposed to be correct in the first place when I paid for it and pretty much shrugged his shoulders as if "sucks for you". Thanks Leroy Merlin for making me incur extra cost on an already expensive process. Let me just say you have lost a a group of customers and seems like you don't care.
