Complaint. ******* policies

I bought a gaming mouse and It didn't work so I returned it and bought a more expensive one paid the difference and still same problem mouse doesn't work and I returned it again and asked for a refund to which they refused. I had a fight with the manager saying it's ******* to have a no refund policy to which she said she can't do anything for me. They don't have a email I can provide but here is their contact details +***7
