Overnight became over week

We bought a gift in bloem on the 13Jan2016 that was put on the courier scheduled for over night to Kuruman,<br> Late Thursday we phoned to ask about the delivery and were inform it will be here on the next day Friday. needles to say Friday became Monday and now we at Wednesday again and still no delivery. i phones the customer call center twice, one Mary said that they will get back to me within an hour, 5 hours later i phoned again just to be put on hols for 15 min. way don't you just tell me what is going on.... is the packaged lost? the worst part of all is Monday we had another package from Lichtenburg with a courier that i have never heard of (courier guy) and it was delivered today. <br> tracking number ***
