Premio S85 is faulty

I bought a Premio s85 in July. had nice specs for a R1099 phone and I thought it was money well spent. Month later, it started having problems. it would freeze until I took out the battery and restarted it. late August, the problem got worse as it froze several times a day. sometimes it would not freeze but all apps would refuse to run until you restart it. Also, the battery was so swollen after only two months.

I took it back and because I did not have the accessories and the the box the refused to take it. I don't live close to the mall and all I wanted was am explanation of why the battery was swollen and they should replace it? Clearly there is a factory fault with the battery because this is not the first complaint even here on hello Peter which brings abonxern. I am a new mom and travelling to Clearwater with a new born baby.
