Very unsatisfied customer

I placed and paid for an order on the 23rd December 2018 schedule delivery for the 28th December. I received an email yesterday morning at 11:30am. Telling me my packages is on it's way to me. I tried tracking my packages I was unable to I tried calling my calls were just dropped I sent an email still waiting on a reply. I am furious and very disappointed in your services. It's my mother's birthday today and I have no idea when you guys will deliver. I am on holiday in Port Elizabeth my mother's in Cape Town i am missing her birthday but thought i could surprise her with a special gift thanks to you i am unable to. So what do I tell my mom " oh i bought you a gift its stuck in a truck somewhere" I fail yo understand sending me an email saying my packages is on it's way so what happened did the truck make a pit stop. It was easy for you to take my money but clearly you dont care about your customers.
