iPod Battery Depot Shipped me a battery for $23.94. Battery is completely dead, no answer at 888 number and no return instriuctions. Internet

I ordered an iPod battery from iPod Battery Depot on line. Cost of battery and shipping was just under $24.00 and came with an advertised lifetime guarantee and 60-day return policy. I took the battery to an iPod retailer to have it professionally installed. The IT specialist advised that the battery was completely dead and would not take a charge. I have attempted to contact iPod Battery Depot in order to obtain return instructions. However, the number provided on-line is answered with a recording and the only option provided is to leave a message. Contrary to information at www.ipodbatterydepot.com, you cannot speak with a "consultant" at the number provided. I have left multiple messages, but have not been contacted.
