My motor started dying the other day when I was using it

I kept thinking it was maybe a problem with the wall outlet I was using or the cord wasn't pushed into the pump enough - nope... definitely dying. I read of this happening to another woman around the same time span of usage (6 months). Totally bummed and annoyed. I went to Babies R Us and they wouldn't help me, told me I had to contact the manufacturer. I contacted Avent and have yet to hear back from them days later, even though their website says 24 response time to inquiries. I need a working pump, so I just went ahead and bought one on ebay. I sure hope the seller ships sooner rather than later.
