Disgusted in Telcom Technical support

Telephone and ADSL line cutting out on a daily/hourly basis during the week and especially on a Sunday. Sundays are a huge problem and more frequently than in the week. I will log a call on a Sunday, they will send a technician out during the week and inform me that they have not found the problem, from there I would not receive any further feedback until my next call the following Sunday logging the same problem. No assistance or problem solving from Telkom after numerous complaints and calls logged. Call centre agents are no help regarding this problem and I need experienced technical support regarding the above query but getting nowhere with Telkom. This is extremely disappointing and unprofessional.
