Unacceptable Service Very Bad

I made a booking for collection on the 19th of September via Client Zone , I have been phoning since then to know when my parcels will leave, and nobody at DSV is picking up any line. The one day I actually came through on the lines the lady told me that there is a huge backlog, but this is not my problem as I only have a (x) amount of days to get my parcels to JHB. This is totally unacceptable.
