Don't use them. This really is MONKEY BUSINESS! I went on their wecbsite to book a collection and the item weight is 11kg but I couldn't shrink wrap it back into the box. The supplier agreed that I can tape the bag and return it to them. K then contacted Parcel monkey to say that the weight of my parcel is the same but the dimension is different - should I cancel my collection and rebooking? They said the courier will tell me the price different when collecting the item. The courier arrived and just picked it up. I showed him the box that it couldn't fit in with weight and dimension and he just said it's fine! A week later, Parcel Monkey wrote to tell me they charged me extra £53 because the new dimension means that the weight is 25kg. I forwarded them the email from the supplier confir ing the weight of 11kg and they still insisted nothing can be done!
