Worst Service Ever! I want a refund!

I want a refund from Ikhokha! I ordered two Shaker Solo Machines - and waited two weeks to receive it. I called daily , but was told the consultant Nico Pillay that assisted me was nit in but “please send me an email with all the details and I will sort it out for you!” by every single consultant I spoke to. I sent 5 emails to 5 different people , to this day nobody got back to me except for Nico the Friday (a week later) advising me he was off sick! I bought the machines for a function I needed it for that Thursday that passed. On Monday our machines eventually arrived. When we used them this weekend on a festival, it worked for the first few hours of Friday and the first machine died - never to come on or charge agin. On Saturday the second machine did exactly the same. Monday Morning came , I sent an email and called Nico Pillay, where he advised a service consultant will call me. No reply on an email or call back once again. I WANT MY MONEY BACK AND I NEVER WANT TO DEAL WITH IKHOKHA AGAIN! WORST CUSTOMER SERVICE EVER!
