kwi cot gerysers disgusting behaviour and faurdstad

we have purchased a gesyers in April 2016. and the geyser was still under guarantee and it had a 3 year guarantee. the geyser started licking. but before this we had an problem where some one came into oour yard and ****** or pressure valve that works with the geyser. and at that time we did not have any funds to put on the pressure valve. so I did call kwicot. they said it fine my gesyer is still under guaranty and one for they guys will come out and put a new one on for me. so the next day they guys came out he said my dad where the pressure valve we explained him the problem he took picture of every thing and he gave us a note saying we need to call he's manager for authorization. so I said fine we will do that. I call the manager he was really rude i spoke to him told him exactly what happned he said he need to get back to me I said fine. he did not call so I call back. I spoke to a guy buy the ne of ridwaan he said they only way he can help me if he give me a demo gesyer so I asked him why a demo and not a new gesyer coz my gesyer is still under guaranty he said because there is no pressure valve he can't give me a new gesyer. than he was a bit funny with me he told me I must get my plumber on site and ask him to call me. I call my plumber on site he called kwi cot they told him since there was no pressure valve and ur job is bad the guaranty and warranty falls away. when I call my plumber here he charged me a call out fee of 200 rand. so I called kwi cot back again I spoke to the branch manger he name is Raymond he was rude once again. I asked him why when I spoke to ridwaan he said he will give me a demo gesyer and now u telling me some thing else she said ridwaan was not supposed to tell u that. he said to me how does he know if they was a pressure valve there when we.bought the gesyer i told hom we bought is all on the same day my my plumber installed the pressurw valve and gesyer on the same day I explained him the pressure valve got ****** he said its not he's problem i said I do understand that but the guaranty is not on the valve or my plumbing the guaranty is on the gesyer is self. he said that not the point and he went on and on. and he said that there nothing they can do i even told him i am put this problem on hello peter he said he not worried i must do what i need to do. I am really upset with the service i got from kwi cot. i mean we all are only human we don't ask for these things to happned but it did. I will never ever buy a kwi cot gesyer again. it's almost a month and we still do not have a gesyer.
