Poor service

I have had such a bad experience the last few days with Dawn Wing delivery service. I have spent more than R1000 on airtime phoning customer care trying to track 2 parcels. The drivers log that they "deliver" the packages but my work business is closed or they cannot find the address. I am at work everyday from 6-5. I had a phone call from the branch manager saying my deliveries will be delivered first thing but the tracking shows it hasn't left the warehouse. I am so angry and disappointed. Oh no that's an understatement.
