Huawei — providing false information to sell products

I have purchased a smartphone honor 9i few months ago. Mobile was good in functioning but charging option was the worst part in mobile. It takes nearly 180 mins (2 and half hours) to charge the mobile from 0% to 100 % which is too long compared to any other product. Once i came to know about quick charger named huawei quick charge ap32 being sold in their honor online store. After enquiring from the customer care about its support to my smartphone, i ordered one and received it. But it didn't charge my mobile quick. Customer care executive asked me to bring it to the authorized service center. They verified and gave me a replacement. Still, the charging time of the mobile is too slow as before. They are selling a product which is not compatible to my smartphone.
