Don't buy anything from Flipkart

Dear all I just wanted to share my recent experience with Flipkart. I recently purchased a split AC from Flipkart which they delivered on 7th April and assured me that within 24 hours my AC will be installed against which they are charging me 1900 rupees. But till today (10th of April) I didn't received any call from them neither they are allowing me to install it via third party by giving an excuse that my warranty will be voided if I do that. I called them several times on their TFN and each time but either I'm not getting response or they hung up my call in middle of conversation. Flipkart services are disgusting and on top of that their service executives don't know how to speak or resolve a problem, all they know is hung up a call when they are speechless. Amazon is far better than Flipkart and I don't think Flipkart ever gonna touch the level of Amazon services in next 100 years.
