bad attitude and general bad service

I bought a Samsung Galaxy Alpha in May of this year (2015) not even 6 months down the line the button has broken, I took the phone to Samsung Nicolway (H/O) where they assessed the phone and advised that we call the call center regarding replacing or fixing the phone. The guy i spoke to was blatantly rude and told me that my warranty has expired. It hasn't even been 6 months and the phone is under warranty for 24!! When I asked to speak to a supervisor or manager he then refused to put me through to someone and said that I obviously \don't understand plain english"referring to my \""expired\"" warranty. I'm absolutely appalled by this service received! I really do hope this is resolved to avoid further complaints and inconveniences :( I thought this would be a simpler and friendlier process! """
