Promotion offer for December free Flight Centre voucher no voucher given. (Vodacom, Samsung, Incentiv)

I purchased a Samsung Vodacom Contract that promised a Flight Center voucher of R5000.00 and that was supposed to be SMS'd to me. I never received the SMS. After Two month I went back to the store and they informed me its not their problem and called a Samsung guy. The Samsung Guy said its not his problem and so emailed some promotion guy. Some promotion guy phoned me and told me its not his problem but the store's/my problem and said he would send me an email stating that. The promo guy who phoned me did not send the email, and didn't phone me to do a follow up if I received the email and didn't really seem interested in helping me. (Poor service, I am the one inconvenienced here)

Basically he explained that I ("my fault") should have collected the voucher before the 6th of February (this was not communicated to me by anyone and the SMS was suppose to have been sent not "collected") even though the voucher is valid for a year. He then continued to say that it's the store's (where I purchased the contract) responsibility to make sure I got the voucher number. So basically I am getting the run around from everyone since the store told me it's not their problem and he says its not his. I will opened this complaint against Vodacom, Samsung, Flight Center and Incentiv. Poor service and coordination among these partners. (Centurion Mall Vodacom Shop))
