LT Online Store — Faulty printhead received order no.[protected]

I had placed an order for HP printhead kit combo pack, 3JB06AA from my HP deskjet printer number 5821 on 6th Jan. After multiple follow ups i received the product on 23rd Jan. However when we installed the printhead in our printer it was faulty. We kept getting error.
Immediately i wrote to LTonline reporting this matter and asking them to replace the product. I also tried calling their customer service and whats app but not one is responding to me. My work is getting affected and my money us stuck with them. please replace the printhead urgently or refund my money
