I have had some experiences with sending packages earlier, without any problems. After using ParcelABC, I can safely say that this is the WORST package delivery company out there. The prices might seem cheap, and they might answer early on, but do not get fooled. This company of horrendous service did not deliver my package for over 4 MONTHS (And yet has not delivered). They started by stating that the package did not have sufficient information, although it did.
Furthermore, after days without answering, and me sending all the information possible, I asked for the package to not be delivered, and rather having a friend of mine picking up the package from where Parcel picked it up. So, what did Parcel do? Well, they understood that this was a possibility for them to lose money, so they would rather keep me without being answered. After sending tons of emails and calling a million times, I could not reach them anymore. Pretty pathetic for a company claiming to be professional.
To summarize, if you ever use Parcel and actually receive the package, you can consider yourself a lottery winner, as the chances for either one are equally small.
