Bad support for bugs

I have reported about a bug in chat conversation week ago and there is no single response till now,it shows you how the chaos that this app about from the inside,buildingor designing an app and getting a respected amount of money or popularity in return doesnt mean that you neglect the "bug fix" concept or not even giving it a priority,this issue happened thrice for me till now and there is no a single solution for it.
