Vu Televisions — Had repair few month back paying huge amount and now again tv got issues

I have recently replaced vu power supply as tv stop working there technician advice me too do so
They remove the original part and replaced with the new one and took the old part with them
They charged me for full new part also
And also took the old original part
I complaint for this too vu company
But there was no response

Again now my tv had stop working
And asked for technicuan visit
They told there visit charges are 1500
And if any problem parts will be charged

So it's like buying vu tv has frustrated me
And really a great loss and dissatisfaction
Wen there is problem in tv you should atleast solve the problem with best efforts and low cost
Thats what company after service should be reliable for
But here I am really upset in great loss and really unsatisfied with service of company

Wi will never ever suggest anyone to be part of vu company and share this experience with everyone
