Cashback not received, #2

Hi, 

I purchase laptop in chennai, ashok nagar branch (near ashok pillar) (TN, India) branch and the branch contact person name is Karthik (9884098069). He said same as 10% cashback on icici cards after 90 days. but 150 days gone and i didn't get the cashback. when i call him regarding this no response from him and also rudely talked with me. 

after this, i recommended my friends to buy another brand of the laptop instead of dell because, dell brand is ok but some of their staff behavior in their showroom not good.

Please take a look on this type of issues in feature, it will effect your brand name.

Thank You
