STILL NO RESOLUTION - 2 MONTHS LATER

I am still waiting for a resolution for my parcel which went missing 2 months ago. Since then I have had a response on here promising me that the supplier's claim section would be in touch with me. They contacted me but said that there was no resolution as they were waiting for a response from Postnet. Once again, no one is taking responsibility. I called the original customer service manager who was supposed to assist me (the same person who emailed me once and stated that she would call me back on the same day...this was more than a month ago and who has ignored my calls). She then said that I had to call Postnet myself to get resolution. What is going on!!! No one wants to pay me back. I am at my wit's end. I have to stay composed when people don't give a dam (Sp!) and who insult my intelligence by saying that I don't listen. I have it in PRINT. I sent all the claims documents. I have called numerous times. No one is paying me back for my parcel, for the service which was not delivered and the hours (yes I've accumulated hours) of phone calls to find out what is happening with my claim. PLEASE HELP SO THAT I DON'T HAVE TO DEAL WITH YOU EVER AGAIN.
