Very poor customer service!!!!!

I ordered a parcel online as I always do and saw dawnwing is the courier company. Never used them before but usually I wait maximum a day as airfreigh is flown in and delivered the next day. No parcel came so I started phoning track and trace- I kept getting replies no. \we will call u back". My parcel is urgent and needed. I asked wether or not something orderd on monday can not be here by friday. No awnser untill someone mistakenly told me they sent my parcel to the wrong place. I spoke to a few ppl who knows nothing. Trudie at cpt branch customer services manager keeps sending e-mails to jhb with no reply. I was promised by a call centre agent who they told to phone me that Adelle customer service manager at jhb would call me to no avail. They dnt call back at all"
