no warranty

I purchase a 6 kw inverter (R16000.00) , after two weeks of doing payment and a trip to cop station the inverter was sent down. second hand unit , I installed anyway only to find charger was not working. I sent it back and was then told I installed it incorrectly and that it had no warranty. I have done more than 40 installations and not one fault, and it is impossible to blow up charger unit and not complete unit. I am now told that they will not sort it out so I have gone legal route and have had to resort to methods like this to warn others out there. There are a lot of honest suppliers out there just a pity I got the wrong one. Now that legal route is on we are getting stupid offers. Think somebody needs to read the CPA.
