Bad Service, Communication and ******* Workmanship

On Sat 5th March I asked Mandla if they will come and complete the screed on the 7th He said he will phone me back in 10 mins. Never received a call so I phoned him again on Monday and confirmed he will send the team on Wednesday @ 08:00 My builder came out specially to meet with them. After phoning 3 times, pleading politely, They arrived 11:30 - There is my builders time also wasted.They then laid the screed 3 Days later there are still pools of water and the places where the screed managed to dry started to perish I have paid in full (excluding the skirting as I am thinking to go elsewhere for skirting at this stage) R64,289.62 and the Vinyl stick down will definitely not even last a week on screed that 3 days already started to crack and perish that you can lift with your fingernail! Yet Mandla says it is fine!The previous screed they laid when the supplier was with them, was done properly.I still need to have the staircase done yet the current area is a mess and wonder if they will ever get the staircase right not to mention the remaining bedrooms! On my invoice I was billed for a 5lt cleaner which I still have not received! alot of money for a really bad experience so far!
