KFC India — Free zinger Burger missing

Address:

4/11b bijoygarh

Dear Concern,
Have ordered Wednesday bucket today through website, but haven't received the free zinger burger, as its showing with every offer free zinger is available. If you people are not providing the free offer what you claim then what's the need of the website. And as discussed with the Lake mall person, they said there was a tick option to avail the free burger, which may be I haven't ticked while placing order, but again after the call I have gone through the website and tried again placing order but haven't found any such option to tick for the free burger, I do have video to prove, as I could not understand if it is free, then why I need to tick or say yes I want my free burger, this is to fool people. Such horrible experience. Being a regular customer never faced such experience. Will definitely post online so that people should know that how you people are making fool us. I want my zinger burger, kindly inform when you people will deliver my zinger Burger.
Need mail id where I can share all the video proof.
