Nashua Cape Town - disgusting!

I have never in my entire life been so disgusted with a company, but Nashua takes the cake. From selling me a faulty inverter that has been crashing my equipment, to ripping me off with their contracts and deductions. I record all copies made yet come end of the month suddenly I am charged for way more copies than I made. A Mecer inverter that does not even cost R6000, Nashua is charging me over R20,000 for - this is daylight ******* and quite *****ulent!! Will not recommend them ever!
