Terrible after sale service

I bought a dishwasher from Makro in August. Within 2 months the dishwasher started leaking. I contacted Hisense and they sent someone out after almost a month. The person said something were upside down and fixed it.

The dishwasher started giving problems again as it did not work right. I logged a call 14 Feb, giving my contact details. I went on leave and saw they send an email asking for proof of purchase which i already sent to them. I resend again 28 Feb. To date, a month later I still have not been contacted.
