Apparently there were many "acts of god" last week in memphis with thunderstorms between Tuesday and Saturday. Of the 3 packages i mailed on Monday, March 31, two showed up on Wednesday and one on Thursday. Mailing back Friday to Saturday...received packages on Monday. I was given every excuse from bad weather to beyond our control etc. They asked me to save the packaging from thawed out biological samples that were all over the inside of the cooler. I finally told them that i was mailing a complaint to the CEO of the company and SENDING UPS because i knew that it would get there overnight. Maybe that will get some results.
