False Adverting by Vodacom

On black Friday Vodacom had many black Friday deals online which were breathtaking, i app**** for the Huawei P10 and P9 deal which was 279 for both. I got an email with a ref number which stated that if i dont get a call back from Vodacom in 24 hours i should call them back on a certain number which was on the email and state my ref number, i have been trying to get hold of Vodacom since Saturday on that number and i was put on hold for over 30 minutes and ended up giving up. Today after holding for almost 20 minutes i got hold of an agent who told me that the deals are no longer available as the deals were only for Friday. What i don't understand is I placed the order on Friday and waited for Vodacom to call me back on the same Friday, then how is it my fault that they never called back on Friday and they clearly stated on their email that if they don't call back in 24hrs i must call back 24 hrs from my understanding would have been on Saturday. I'm really dissapointed with Vodacom i have been a vodacom client for more than 10 years now. Vodacom must stop false advertising.
