Huawei — honor 7x charging very slow

Address:

I bought honor 7x on 13th apr 2018. It was good for 2 days. And now in a weeks time. For charging from 0 to 100 its taking 6 hours time. I even used a different charger and tested it, the results are same. The product description says it will get charged fully in 2.5 hours. Product with a good company, for sure if you are selling these kind of products, your goodwill will vanish soon. I need an answer for this at the earliest.
