Incompitant Service

I bought my Hisense U988 March 2015, 2 months later the phone doesnt want to charge and pick the USB mode up, i than booked it in at Rectron, so they send it to Hisense repair centre in Chloorkop, not even 7 working days i recieved my phone FIXED. 2 weeks later the phone did the same problem, i than ignored it, after the 4th week i send it back to Rectron and they send it to Hisense again, 4days later after calling and fighting to find out whats happening with my phone, i recieved a call the next day with a quote of R1170, apparently i tried opening the phone and there was a water mark on my phone, funny enough all customer who bought the phone from Rectron and phones went fir the same repair twice got the same excuse for Hisense not to fix thier nonsense
