Nothing done about an inquiry

Good day<br> <br> I lodged an complaint o the 19th of jan that I was being billed for data usages were the phone that my sim card was in can not even use data so I asked them to investigate were the data was being used and in the mean time please suspend my sim so on the 23 jan I get a message my sim has been suspended and no other info. I phoned to day to here what is the states on this investigation and thy say the query has been closed but thy did not do any investigation only suspended the phone so now I am paying for a suspended service and Telkom is getting the money but I am not getting my answers . This is unacceptable. I have 3 contracts with Telkom and if this is the service thy provide I do not think I will be renewing any of them wen thy are up
