Vodacom - Poor Customer Service

I ordered the Black Friday deal on 29 November which is R125 for 250 minutes monthly, my order history states "SUCCESSFULL", Order Nr E***7, and I chose the option that the amount should be added to my bill. By the 1st of December, it has not been allocated, so I called Vodacom, but no surprise there! They cannot find any order, although it shows Order Successfull, now they say I should have lodge a complaint the same day, but how should I know that? I thought it will be allocated then on the 1st of December, but according to them it was too late. Now I ask the manager, is there something else you can offer that is more or less the same, as this is a mistake on Vodacom's side, answer is just NO, I have to say the service is pathetic, you have to hold on for someone to answer for about half an hour, and no customer service on their side! And I have been a customer for many many years, but I have to say, Vodacom is nowadays a big disappointment.
