Sangeetha Mobiles — cash back refund

Address:

Chennai, Tamil Nadu

Hi,
I bought mi a1 mobile from sangeetha mobiles (Royappettah branch) on 8oct17, at the time of purchasing mr karthick (Store manager) was very polite with me and he said if you buy mi a1 you can get gifts like vr box, temper glass or selfie stick.
At the time of payment he said me if you pay through hdfc credit card you will get 5% cash back and at that same time he didn't told any conditions, he told you will get cash back within 1 or 2 months thats it.
After his kind words i trusted and purchased mobile and asked him to pack mobile with gifts then he said as of now we don't have gifts once we get i ll call you then i trusted and left from the store, after than many times i called him to ask about gifts he always said we have kept stocked in adyar branch go and get there.. I said i purchased mobile from you so you have to get it from there.. He cut the call there is no response.
Then i visit store many times and waited for more than one hour to talk with him but mr karthick wantedly avoided me to talk and his very careless also then i fell very bad.. Now around 5 months over no proper response from mr karthick.
Recently i visit store and asked about cash back money he is asking transaction slip they didn't inform anything about the slip in previous am totally unsatisfied and very unhappy with this type of assistance.. I request sangeetha team to please follow-up my query and refund my cash back money along with gifts..
