Non-existent customer care , unhelpful staff , holding on line for minutes , no call back

on black Friday there was a special for a Nokia 8 Sirocco 128GB Smartphone for R165 , I requested a call back as i couldn't get a hold of Vodacom the entire day to take up a contract . I was not called back .. Came Monday i didn't get a call back nor could i get through , finally two after two hours i got through , and was told by the sales agent that i didn't get a call back because the phone was sold out( bare in mind a tried when the sale had 5hours reminding to take the deal which i even have a picture of) , he then stated 100s of people didn't get a call back .. Customer service is non existent clearly .. asked to agent if there was something we can do as this wasnt my fault but on vodacom's part ,Agent said no and had no remorse what so ever , thinking i found my deal i didnt look for other specials , now i am left phone-less Because vodacom didnt think it was necessary to call me back .. and me holding for minutes with no phone

Wondering why people referred me to Vodacom
