Poor service.

I bought a new Karcher high pressure cleaner, last year December. Within a month the machine started leaking water within. the unit was returned to Macro Wonderboom for repairs. At the end of January i received a call from there staff informing me of a quote for repairs. When i inquire to what was wrong they could not tell me. I refuse to accept that i had to pay for something that was less than a month old with internal failure and at almost the same price as what i paid for the machine. I was informed to come and see "Florance" a manger at Makro. On arrival subordinate approach me and inform me that this person is busy and that i had to wait for there manager "Shipo" "Shipo" came to see me and assure me that he will resolve the matter for me and that it was unacceptable. We are now at week four and once again no feedback from Makro staff. Can someone in Makro that still believe in customer service get hold of me so we can resolve this matter. Thank you.
