Fault closed without resolution

Logged call with Telkom on the 29th of march for a telephone line being fault. Call was closed on the 3rd of April with resolved status without checking with the client that the problem was resolved and on top of this the adsl is now also not working which in my mind means the technician has worsened the fault. new call needed to be logged and cannot even escalate. this is unacceptable and extremely poor service and to make matters worse this is the fourth call in four months. this is impacting my job.
