Worst Service

Vodacom is absolutely becoming the worst. If it were up to me I wouldn't even give them that 1 star because a star is better than nothing which is what they deserve NOTHING. So I take an advance from vodacom worth R5, gets approved and goes straight to my balance. Now I have R5 in my airtime. I try to buy their Just 4 You bundles for my town which is what I always buy 250mbs for R5 but it says I don't have enough credit or airtime to make that transaction. I am confused at this stage I check my balance and it remains R5 so I call their customer care and the guy helping sees my airtime to be R5 agrees that my airtime is R5 and tells me that he doesn't know what causes that error then he asks me opt in and out from data lock or something like that so we do that me and him while on the line after doing what this guy told me to do my 10cent is missing so this means I can not buy the data bundle because its 10cents short. Now he says that is the reason it kept failing but he saw exactly that I called him with a full R5 balance. I am not happy with this. And i want this taken forward because I will have to buy for the advance which did not serve its purpose.
