This is really worst experience with mygubbi i have paid 100% amount for my 2 bhk flat at pune and i am following him daily by mail/call/message since last 4 month but now nobody is receiving my call and neither they are replying by mail nor message and and chat.. Nobody is receiving my call neither from pune nor from bangalore office.. Nobody is giving update on my furniture there is coordination between pune and banglore office team..
I am really not sure what i have to do and how i can get back my money
I mail several time to cancel my order now and refund my money back but still nobody from there office replying
