Despicable service from Netstar

I am a long standing Netstar customer. I was at some point last year, advised that my account is in arrears and that services have been terminated. I immediately provided proof of payment to them. Since then, up until now in June I have repeatedly sent the requested proof of payment and to date the matter has not been resolved. My services have in the meantime been terminated even though my account is up to date. Every time I follow up I am told the matter has been escalated. I have been communicating with Mathapelo Masipa who is in their Finance department. This is terrible service from Netstar, I would Not recommend them to anyone.
