Horrible service by iMix Sound and Lights

Horrible service. I took my iMix 16 Channel mixer for repairs early June 2021, 4 Channels including one main output was dead. They told me couldn't fix the specific channels so they'll change the whole board and charge me R1700, I was not happy, but still went to collect it, The Chinees manager was very rude and he kicked me out when I requested for testing before, i pay for it, and yet when they tested, the mixer had buzzing noises.

They ask me to leave for further testing, and after almost 2 months they called me and said I should come collect. When I went to collect I was told the that should now pay R3000 with no one to explain why. Of course I was not going to pay R3000. I asked them to keep it. I wouldn't recommend anyone to do business with this Company called iMix,
