Frustrated and disappointed

I purchased a Goodsky blackhead remover instrument from Makro and what a bad experience, it is the first and the last I purchase anything from them. Upon my purchase i had issues with delivery, the courier phoned me at 9am, the driver went to the wrong address and gave me an attitude when I told him, he then said why didn't you specify, which I did on the Makro site and somehow it changed or disappeared when I checked, I even made a special instruction, I then emailed Makro customer service and still no response. the driver then said he will deliver later that day after 12pm, I waited and he never came, I phoned the courier at around 15:30 and asked the guy working at Dawn wings courier(I assume he is part of customer service or deliveries) why the driver never came and he ensured me that he would contact the driver and make sure he delivers, driver came after 16:00 with an attitude, received the product that day which was the Friday and the Tuesday I decide to use it and guess what???? It does not wor****!!!!!! Pathetic to say the least. I want to know what happens from here???? Never again and will sure tell everyone I know about this pathetic service! I want my money back!
