Complete and utter rubish

We bought an apartment of which Tasol was the suppliers of the UPS solar system. It made such a huge noise that it was unbearable to have in on. After a battle , they agreed to replace the Unit. Now almost 7 months later , conveniently out of their warranty period , the units breaks and is completely dead. This is a ******* product!! When questioning on whether they will fix it , the just reply and say the 6 months warranty is over, fix it yourselves. Having a product of such nature with such a short warranty is also completely stupid!!! Bad product!! Bad service!! We are als not the only complaining in the Estate and most are complaining that their units are either broken or never worked from the start. DO NOT BUY FROM THE COMPANY!!!!
