Very poor service from HiFi Corp Technician

Hi, I write this report with great sadness & disappointment.

I went to Carnival around 8th Jan 18 to book a 55 inch Samsung TV (bought around 2014/2015 at HiFi Corp). Then the repairs department said why can't I get a view from their trusted & recommended technician i.e. Asanda ********** . Then Asanda took the TV on the 10th Jan 18. I have paid the call out charge R400 plus full fee of R3900. Now Asanda doesn't want to bring back my repaired TV as everyday he comes with excuses etc. I have called him several times with no straight answers. Recently he doesn't take my calls or reply SMSes & Whatsapps.

If Asanda fixes Hifi Corp equipment as I was given his number at HiFi Corp. I am humbly asking HiFi to assists for Asanda to bring back the repaired TV or unrepaired TV with full refund.
