I have mailed several birthday cards to a Frenchtown NJ address, They never got to the addressee. Where could they be????


I'm s sick of the temp mail lady who refuses to drive her lazy butt up my driveway to reliever vital signature required mail. The stuff being delivered requires me to respond within a shirt strict no room to extend deadline and she continually just leaves the oh we missed you note. I've lodged one compliant, still happening. Tomorrows complaint won't be as friendly as I will be calling the post master Monday and going through higher channels. Laziest mail person I've ever seen. To ignt she decided she didn't want to deliver the neighbors mail to the box next to mine so she went ahead and rubberbanded both separately (gee thanks for taking the time and making it easy for me to separate) and then put em all in my box. Um a I getting paid to deliver the mail? No. Am I getting paid to do your job? Um nope again. If you can't do your job you shouldn't get paid. I'm done with this crappy mail service.


Be careful when you mail packages from Frenchtown, NJ. The woman told me it was $6 to mail my little package. Wow, that's an awful lot to mail a 6 oz box. I don't recall asking for it to be mailed via Priority rather than the less expensive way--First Class. Milford is more trustworthy & always gives me my postage options rather than charging me for a more expensive service that I never requested. Frenchtown has lost my business.
