No funds for delivery???

Our parcel from overseas has been cleared by customs on the 15th December 2015 and up until today has not been sent to pta hub or our post office....the reason JMC at O.R Tambo told the Tswane hub that they do not have sufficient funds for extra delivery vehicles to deliver back log parcels. So that became our (the customer) problem. We have a workshop and need our parcels asap. And South African Post office cannot deliver a service they are suppose to. It is not our responsibility to drive over 100km to pick up our parcel and pay them for a service that they were suppose to deliver. It is pathetic. We are located on the other side of Pretoria North, and it is a long drive to JMC. We contact PTA Hub for updates and they cannot give answers because Johannesburg Mail Centre cannot tell them what or when it will be delivered orther than that there is a back log and they do not have the money for the other vehicles to deliver. So now we need to take time that cost us money by hour to drive to JMC to collect our parcel. This cost extra money from our pocket because they cannot do what they are suppose to do!!!!! What are you (JMC) going to do about this????
