Disgusting Samsung customer service (MM All Electronics)

On 28 March 2019, I took my Samsung washing machine (model WD8704EJZ1/XFA serial number Y4TP5ADBA00021H) in to your official Samsung repairer MM All Electronics in Sandton (Wedge shopping centre) and paid a +-R250 fee for assessment. My customer reference number is ********** 164. More than a week later on the 5th April 2019, they provided me with a quotation for repairs to the value of R2809 (quotation number 15079). I paid the quotation in full. On Monday 8th April 2019 I collected the machine. They assured me that it had been tested and repaired to the highest Samsung standards. I took the machine home and connected it. When I did a test wash, water gushed out from the bottom of my machine all over my kitchen floor. I telephoned Samsung customer care on 0 ********** and complained about the disastrous repair and was issued reference number ********** 717. I was assured that this would be sorted out within 48 hours at no further cost or inconvenience to me. It is now Thursday 11 April at 18h20 in the evening, and despite numerous calls to 0 ********** nothing has been resolved. I am R2809 out of pocket for a botched repair and my washing machine is still standing broken in a puddle of water in my kitchen. Absolutely disgusting service. Samsung should be ashamed. I hope this is escalated to the highest level.
