Query: Customer Service Stinks-Product FAILED

I have had my MacBook for 6 years and only needed one cord. I ordered from this company to replace the original cord as it was worn from the dog chewing it. The cord that they sent lasted less than five months. I contacted them for a replacement and they didn't even bother to reply. Won't be ordering from them again.
