They cant help me , or refer me to the next person

I loaded airtime and bought data twice , most of the day , my mobile data was off and the whole night lastnight it was off , I recieved a message that I had 4,99 megabytes of data left and shortly after that the balance was depleted , which is normal , so the first 30 meg I bought was finnished . I decided to check my balance to see how much of the second bundle is left only to find that I have zero bundles and zero airtime. I called vodacom to explain to me but the consultant told me he cant help me and the floor manager is not in , but my data is gone and they didn't even notify me, cant explain why only one message of notification came in whereas I bought two and the consultant also said on his system I only appear offline this morning , which is a lie . I feel that they are taking advantage of people cause they think we will give up on our complaints , it is so unfair because I bought that data with my money and they are just very unfair for not even explaining what happened to my bundle .
