I ordered a lenovo legion y450 laptop on the 30th of september. Even after waiting till the expected delivery date didn't receive my laptop. On the last day of arrival i received a message from amazon that an delivery attempt was made but till this day haven't received a single call and moreover when i tried contacting the deliver person his phone came switched off multiple times so how was a delivery attempt made. Even after 3 days and calling the customer care for 4 times no progress, updates were made. I was assured that my product will be delivered by 9th october's evening. As of now the situation remains the same as still i haven't received my product. Even after complaining multiple times such poor service has been provided by amazon. I am highly disappointing and sad to receive such kind of treatment.
