Poor online service delivery

I ordered a Fitbit Versa from their online store, on the 29th of January 2019. The parcel was supposed to be here in 3-5 days, so on the 5 day mark, I phone to ask about the experted time of arrival they told me within the week. Sent an email the next day as I was expecting a message regarding the delay but no notification was received. They rep**** that they will give me feedback (which I'm still waiting for) and sorry for the inconvenience. I then phoned yesterday and asked them for feedback, they said the courier is waiting for information from the depot. I emailed this morning to find out what was going on (10 days since date of order) they apparently followed up and would get back to me with feedback which I'm still waiting for. I'm highly disgusted that a huge company like TFG Foshini's group has such a pathetic delivery system in place regarding, online orders.
