Farewell real customer service

I bought me 100mb to last me till tomorrow when my top up kicks in, I loaded the data and not evens a hour went by and it was up, the only thing I done was browse facebook and respond to a few whatsapps. I understand that 100mb does not last on these new smart phones due background data and apps running concurrent however I made sure that my main apps were restricted from background data as it's only 100mb but it doesn't explain how it can deplete in about 30minutes of loading, no downloading or streaming, simple browsing. I called vodacom 'customer service' and spoke to an individual named Valerie, this individual had no customer service experience from the get go, clearly just there for a paycheck. After no progress from this individual I requested to speak to a manager and to my surprise, the usual 'there is no manager around' came out her mouth like it was part of vodacom training. I was transferred to a supervisor named Sindi Buthelezi. She was unable to speak to me as the contract I have is on my mom's name simply cause I do not have debt and unable to qualify for a contract because of this but yet get calls from vodacom offering me VAS (Value Added Services) on a regular. I understand with all the ***** going on they need to do security checks but is that really necessary when I am requesting information on data on the number that I'm using and clearly is displayed in front of them,to me more in-depth information should require security checks, not when querying data usage,that's just plain stupid.. She spoke to my mom and according to her, my mom did not meet the security questions they asked cause my mom pays the account cash in the n1 city mall store, this store too has yet to understand true customer service as my mom has numerous times requested for statements to be sent and to query the balance but they unable to provide this to her... Clearly we as customers are just good enough to fill their pockets with money. Still now my issue has not been resolved and I had to fork out more money to buy more data. I am expecting an answer from Vodacom and won't stop until I'm satisfied, why must they be the only one's satisfied on a month to month basis but we as customers who makes it possible for them to have a jobb, cannot get the service we require. Vodacom, I am expecting answers from you, I have all screenshots I require to support this as well.
