Sinotec pay backyard technicians to repair under warrantee

TV screen went blank, delivered TV to RDC-TV in Paarl for repairs, takes them one week to inform that the TV has to go to CN TRONICS in JHB to be repaired. This is on the 18th September 2017 and when calling RDC today on the 2nd October, I am informed that the TV only left them on the 22nd September? I then call CN Tronics to be told that they do not have my TV and they have no idea where it is? All this took me 6 calls to CN Tronics as they do not answer calls and when asking to talk to a manager, in a meeting, very convenient seeing as they work our of someone's garage by the sounds of things. Very unprofessional repair company. I then try googling a mail address for CN but they are not even listed on the net, no information besides a telephone number. Then I googled Sinotec themselves, receptionist has no clue regarding service, left hanging for someone in service management for no less than 5 minutes at a time. I called back 4 times only to be treated the same each and every time but on the 4th call, I insisted I talk to a manager. I was put through to Naomi who asked for my details and she would follow up with the courier. She is to get back to me. This just to inform everyone out there, DO NOT WASTE YOUR MONEY ON SINOTEC as it is going to be 3 full weeks in 2 days time since handing TV in that is still under warrantee and nobody can tell me where my TV is!!!!! Told it will take 21 working days, pathetic!!!!!!!!!!!! Just received a call from ISSODORE to be told that the TV was found and will be delivered tomorrow being the 3rd October. Tried to bull#$@ that long week-end and all that ****. Still do not know when my TV will be returned to me fixed?????? anyone at a guess???
