Please HELP :). I cannot get the parcels.

Hello
I am writing to you with a small request. When checking on the sledzenie.poczta-polska.pl not determined the weight of the goods that come from abroad. And just as the anger I feel is needed. Perhaps you state the opportunity to check in your system, how much it weighed The particular package. I do not think that did it for you much of a problem and it did not take much time and I would really help.
Here are the numbers you need to know how much the package weighed. They came from early December somehow.
numbers:
RB840473221CN
RB840473102CN
RC008228981CN
RC021267185CN
RC286823801CN
