I bought sony 4k from cumbum branch. They fixed the tv alone. There is no support, how to install, use,. Now it cannot used properly because they didn't give any instruction. Whenever i enter the shop for these problems, they give the phone no for assistance. No use of that no. Please consider my issue rectify it.
