Q: I bought a new battery here two days ago after they told me that the one in my phone was water damaged. Two days later my phone's still not fixed, and I had to upgrade early. They wouldn't refund the money despite buying an expensive new phone. After being a customer 10 years, that's ridiculous.
A:
NEGATIVE
