Last 1/24/2024 the postal carrier forcefully fit a box to our mailbox which is equal or little bigger than what we had provided. We already have the biggest mailbox allowed and yet the package was jammed so tightly it was hard to take it out. I’m glad that the regular postal carrier happened to came by 2 days later while I was still trying to pull out the box out . I was trying not to pull it out without pulling our whole mailbox out of its attachment the next day. So second day , good timing the regular mail postal carrier was there to assist. I was told it was her sub . Hope the sub should not jammed any bigger box into our mailbox again. Why can’t she deliver it into our house even just leave it there on our porch?. I tried calling many times the Gaston post office number but seems like they don’t like to pick up their phone. So I decided this is the best I can do write this review
