No helpful service

Good Day, i have had my cellphone for approximately 9 months. The 1st month i had this phone i had signal problems, i went into the store to fill out a customer form regarding my problem, within a week cell c customer care contacted me about my signal and then nothing changed. I'm still sitting with no signal, so i went back to the store to fill out yet again another form, same out come. I then after about a month went back into the store again for signal and the store manager took my phone for 2 hours, when i asked what was taking so long to fix my signal, she rep**** that she had been updating my software. i don't understand what a update has to do with my signal. I then went back the very next day as now my battery fully charged drained to 15% in 1 hour, the store manager couldn't help me, i was then told they will have to send my phone in and that will take 3-6 weeks to fix and they don't have replacement phones. I didn't send my phone in as i don't have a spare and i cant see how they expect me to be without a phone for more than a month. I have spoken to countless staff at customer care an i have had zero help. I am currently sitting with problems they wont assist me with.
