Reliance Digital — microsoft office mis-sold to me and the men in your store don't know how to help

This is a complaint on reliance digital phoenix market city bangalore.
I had purchased macbook air and office 365 from this store on september 15, 2018 and the sales men in your store are highly improfessional and unaware of the products and it's features. Ittook me from 11 am to 7:30pm to complete the purchase and then install the office 365. The person was not qualified at all.
I had bought a year subscription and today on october 15, i receive a mail that the product is expired and i need to pay again to activate it.
I called microsoft cs and they said the same thing. I called reliance digital and shekhar who is one of the sales man doesn't know how to talk on phone and also is extremely illiterate when it comes to the product. I was told i will get a call back at 1, when i call back at 3:45 he's asking me to come to the store. No value to someones time. The owner of your company knows the value of each second and how to respect others but you guys are spoiling it. I need to get this sorted now and necessary step should be taken to train your sales men. They really need to educated to respect someone, their time and be empathetic to their concern. I will never some back to your store and make sure my friends and family never does to. I will put this poor and extremely not professional behaviour story on social media. Let the world know. You need to shut shop.
