Random credit limit app**** and then softlocked!

I've been a customer since August 2014. My contract is for R249, Internet and phone. Now for last 2 months random credit limit of R432 app****. When data is up, automatically goes to out of bundle rate up to limit of R432, and now soft locked so can't even use my free minutes! <br> <br> I've had to get a Vodacom sim just to be able to make calls! Surely if i wanted to spend R432, I would take a contract for that amount (and probably not at Neotel!).<br> <br> Please change my credit limit back to the agreed contract amount , and unlock my minutes! This is adding insult to injury because 70% of the time there's no wifi signal or phone reception, now you guys pull a fast one like this!<br> <br> Also, get your call centre sorted out: They can't even help me log on, and this is day 3 of the same ticket!<br> <br> I WILL NOT BE RENEWING THIS CONTRACT!
