cell c is *****ing my money

Its been 2 months now cell c is chowing both my data and airtym same tym I buy data everyday it disappears with airtym or airtym disappears while I still have data I restricted my background data but still my airtym disappears I called dem da call centre agent just doesn't help I published my complain at hello peter few months back dey refunded me but da problem still continues am loosing almost 2000 a month on cell c theft . I can't comfortable have airtym on my Fone cos cell c is gona ***** it cell c is a ***** dey also delay the message DAT notifys DAT data is about to be depleted intentionally cos is either I receive the message wen my airtym is already gone or I don't receive it at all. My airtym disappears even when my data is still there it seems like dey start by billing airtym wen I surf internet cell c owes me my hard earned money
