One month and a half still no response

I was contacted one week ago by Eric from the social media team who promised to follow up on the pending case of nearly 2 months and has still not gotten back to. To compound matters, yesterday my data balance was 7.1gigs and today it tells me out of bundle without using it!!!!! I'm sick and tired of Telkom not giving me a solution nor feedback and I want this to be taken higher because 2 months is a long time to wait for a solution!
