Naturals Unisex Salon — gerugambakkam branch - august offer

I went to gergambakkam branch for the independence offer. I have asked to the employee selva when is the expiry of the the offer, before taking service. He said there is no time line for the offer. You can avail the offer whenever you wish to. Later after taking the service he is giving a time line of the offer as dec 31 at that time also i have told him you informed me there is no time line, i don't visit spa often i have asked you earlier about the timeline of the offer. He said by word of mouth madam if you don't avail the offer i will change the date. Even the staff said why do you give false belief to the customer. Now i am not able to take the offer within the stipulated time. Now he is denying that he dint inform me.

Please take necessary action for the above complaint
