Coolpad India — they have delivered me the wrong charger of coolpad note 5 phone

Address:

Ahmedabad, Gujarat, 380003

When i bought this phone they have delivered me the duplicate charger of my phone. First few weeks charging was good and fast but suddenly problem came for the charging. When I complaint to coolpad customer care they told me to go to coolpad care in your area to replace that.
When i visit there they told me that this is duplicate charger as there is no such coolpad logo or sign on the charger, so they refused to replace it. And then when i talk to coolpad care they told me that its been a long days after purchasing the phone and company cannot do such things or such mistake. I don't know whether it happened intentionally or unintentionally but i am not telling the lie, you should not do such monkey business as it will not lead your company to go ahead and your reputation will also get down in the market after these kind of activities. At last i have had to buy the charger because i was not able to find any other way. I will wait for some back comments and your compensation or compassion on my loss. I am also fetching some photos regarding this as proof.
