Data and airtime been depleted.

Good Day, yesterday i noticed that my data was been depleted in like few seconds after loading it. i then phoned Vodacom call center and i was transferred to Technical support of cause like all the time , they could not assist me as system has not loaded my data activity. Now i cant load data and airtime as it will be depleted in minutes and now i'm sitting with a phone which does have data and airtime. The lady(Minnie) could not tell me whether vodacom is experiencing problems, and dont tell me that my apps are chowing data because they off - i know all about that. please look into my data issue and refund me...thanks!!Vodacom has issues all the time haai maan, im paying and not getting free a contract here.
