No International Mail Delivery

What is a reasonable amount of time to wait for an international parcels that were meant to be delivered in 5-10 working days? It's now 2 months since the parcels were sent, the parcels have no tracking numbers (some had customs numbers so know that they have left the counties they were posted from) , and as of 2 weeks ago they still not scanned in SA?<br> <br> There is no point in having anybody contact me unless they can answer all of the following questions<br> 1. Does the Post Office still deliver International Parcels?<br> 2. What is a reasonable amount of time to wait for an international parcels that were meant to be delivered in 5-10 working days?<br> 3. When can we expect the Post Office to deliver in a reasonable time frame?<br> 4. Is there any valid reason that parcels are not being delivered and what is being done to rectify the problem.
