CREDIT LIMITS INCORRECT

6th of May we received emails from Neotel, saying we have reached 80% of our credit limit. Called the call centre who takes FOREVER to answer, costing us money once again. When they eventually take our call they increase the credit limit which we havent even set. 1st of JUNE. Both lines softlocked, credit limit reached! called the call centre several times,holding 20min, no answering. we then sent an email to every neotel email on the internet and finally got someone calling us from the new business call centre. he then gets the operaton manager Alton Green to call us to resolve.At the time very helpful and within in an hour he apparently set our credit limit to R1000 for both lines. on the 4th of June we again receive emails that we have reached 80%, and on the 5th of June 90%. Alton gave me his direct line and cell nr on the 1st of June, promising he will answer when I call. On the 6th of June he has no idea who i am and then says he will investigate. This was at 8:30, it is now 13:00 and he made no attempt to call me back, not answering my calls on either lines he gave me.no replies to my email either. Cannot run my business like this!! DISGUSTING SERVICE!!!
