I am so ****ed off with Telkom and i am a new customer

I am so ****ed off with Telkom right now and i am their new customer. I ordered a WiFi Router and a phone with them last week, they told me it will take roughly 7 working days to deliver which i was fine with. They kept sending me sms's saying my order has been approved and on Wednesday they told me it was loaded on the Courier vehicle for Delivery on Wednesday with number ********** and i waited on Wednesday noting came. Then i called them today with the number to track the delivery and was told they they tried to deliver on Thursday and they tried to call me but there was no answer. I never received any call nor SMS from the courier company. i told them to deliver today and they said no they will deliver on Monday. Why should i wait till Monday when i was never told a delivery will be made on Thursday. i even read all the sms i received from the delivery company and nowhere does it talk about delivery on Thursday. They keep saying there are no drivers and i must speak to Telkom, which i cant even get hold of i dont have their numbers. I am so angry ****ed and dissapointed at Telkoms service and their delivery company and i am a new customer which makes me think did i make a big mistake joining telkom.
