No Service from Telkom and No deposit back for 8 Months already

Our Land line cables were ****** in June 2019 after few weeks getting into the deal with Telkom. Telkom rep**** that the cables will not be replaced and Telkom is not able to provide wireless internet in our area. So no services can be provided by Telkom. In June 14, 2019 we opened the case Ref ***1 and asked to return our deposit what we paid upon signing the deal with Telkom just a few weeks ago. Then were many phone calls to Telkom and emails with requests to return the deposit, but No action from Telkom. They don't deny that deposit supposed be returned, but they do nothing for the past 8 MONTHS. Account ***. Managers, of Telkom - please investigate and refund the Client asap
