Micro fix Pretoria east

Not happy at all. This place took R750.00 deposit to quote my 12 volt fan, I agreed and paid then I paid a further R3000.00 for the repair and as soon as I plugged it in , smoke started billowing from the unit. All good and fair ,but as soon as I returned the unit the very next day hoping for some fault finding and re-repair , Yuri refused to take in the unit to even test it . Money gone, still sitting with a faulty fan unit. As a businessman myself, i Can't believe that businesses still operate like this
