Sinotec warranty repairs

My TV was booked into repair last early/mid November, after I waited roughly 3 weeks for it to be collected by Sinotec, and after numerous calls to Sinotec repairs customer service department over the two months roughly with no valid feedback, I got into contact with repairs manager Mark whom only rep**** to me once after leaving plenty messages and calls, really poor service with regards to warranty repairs. Very disappointing because one of the decisions going with this brand is that it is local therefore assumed parts and service will be more accessible.
