charging un-necessary money for a service rendered

Hi<br> I took my device in for you guys to fix because it was not charging, you did claim to fix it and I paid. I took the device home, plugged in the charger only to find that it was still doing the same thing. I took it back to your repair centre, I called your repair centre and was told that my charger is a generic charger. that is a fat lie because the charger I took in was the charger that came with the device when I took it out on contract with you guys over 2years ago. Again, I am told I have to pay r330 no fault found fee like really! that is ********. why should I be charged for returning something you fixed that was still not working properly when I took it back?<br> If you took your car for brake pad change, you paid for it and on your way driving it back the brakes was still not working properly. when you take the car back to the dealership, will you expect to charged for services rendered again?<br> You guys are ripping people off with this and it is very bad!!
