No Internet connection

We had a Internet line of 30 gig per month- then upgraded the 20th of July to Uncapped Internet. in the 20 days since we upgraded we only 3 maybe 4 days of connection- when trying to phone (min call duration of 15 min +) the phone gets dropped or the call center personnel can not find a solution- we drove to Wonder park Center and they do not have technicians to assist- the drove to Menlyn they promised that the problem would be resolved by the latest busness day end.... but still nothing- we find this poor service unacceptable and would not recommend any of our friends to join Telkom. Poor service...
