Bring back my data and airtime

Vodacom I am really getting tired of you *****ing data and airtime from my phone. I have called your call center Zenzi promised to call back even now I am still waiting for a call back that was supposed to have been revived 1 hour ago. I load airtime it depletes in literally 1 minute. I load data it depletes also in 1 minute. I advance airtime and data still it disappears what must I do? Should I not load airtime ? How the hell am I supposed to live . I called the call center again where the guy assisted me with switching background updates and all but still my data disappears. What do you want from me ? Bring back my data!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
