Dstv Multichoice

Hi was called by Mpho of DSTV sales department on 22 February regarding the pricelock decoder. I was told it would be delivered within 3 working days. It is now the 9 March and I have not yet received any decoder, nor can anybody assist me on where it may be. I have spoken to various people each giving me a reference number of no use. I was called by them this morning and sadly missed it as I was in a meeting. Not being able to get in touch with them as I was again given a reference number... How long should one wait for a decoder? they are quick to sell but extremely slow to follow up!!!!!! I have been a customer for many years but sadly I feel like terminating my contract.
