I ordered a battery for my back up ups and they cross referenced the battery and shipped the wrong battery. This happened on november 7th. Once i received it i emailed them about it and never heard back, emailed again in january and they told me it was past the 30 day warranty period. It was their error to start and i found out that the first email that i had sent was returned. My error. With that said they asked me for pictures which i sent. Then they asked me for the order number and confirmation which i sent. Then they replied that they would see what they could do. Now this came from the sales manager. You would think that the manager could make a decision on this. To make matters worse the battery is a knockoff, and they are not returning my emails. So here i am. I want a credit. Do not do business with this company. Customer service stinks.
