Bad experience

I'm really ****ed/angry with MRP mobile , I bought a phone on the 25th July by the 2nd of August my phone started to freeze , I brought it back to them they took it and told me it is going to take 2 months to be fixed. I asked them to give me a new one they refused. I will never buy a cellphone at MRP anymore. Also their customer services is disgusting . Now all my things are stacked because I was using that phone for job hunting, I can't access my emails as well. Please I need help.What can I do? THank you
