Explora Package order

I am so annoyed at the service I am receiving with regards to the delivery of the DSTV Explora package. I was called by a Multichoice agaent to inform me that my current PVR will soon be outdated and that I should opt for the new DSTV Expolra. Upon taking up the contract, I was told my decoder will be delivered within 7 days. It has been 2 weeks and the decoder has not been delivered, nor has anyone from Multichoice or the courier company contacted me about the delivery. Upon following up with Multichoice, I was told that the delay is not on their side, but rather with the courier company. I'm being sent left right and centre with these calls and no one seems to be helping! This is really annoying and the relationship withh all the parties concerned (DSTV, On Air, On the Dot) is very slack! I am going out of the country next week and trying to get this matter resolved timeously!
