Thunderbolt Display repair in Russia.

Hello everyone. I'd like to tell you story about Apple customer service in Russia. Sorry for my english.

19 November i found dirt under glass of my display, so i took it to apple service center. After a week i receiver my display with new display module. It was terrible, with blacklight leakage and different color light-emitting diods.

After that Apple repairs my display twice, with the same result - that modules for replacement was just worst.

So, in November i received new Apple Thunderbolt Display as replacement. After two month in service center.

And now the most interesting part - that new display is blinking.

Engineer in service centre told me, that i must again replace display module, but apple delivers only defective modules for replacement.

What should i do? I don't want t spend 2 mont without display again and i disappointed in apple quality.

Can someone help me in that situation? Thank you.
