Delayed parcel, no communication and still waiting

I am so frustrated, all because I don’t get hold of anyone, I have been waiting for a delivery from this company, it’s still taking more than it suppose to and their Online tracking is not updated, my parcel is from Herbalife and I can’t get hold of anyone from dawn wing, phones are ringing but they pick up and drop or you hang on hold the whole day, I have sent emails and there’s no response from this company. I do not know what to do as I need my parcel urgently as it’s healthy related products. I’m really frustrated because there’s no communication or even responding to emails. I really need assistance.
