ADSL intermittent since 2 January 2015

The ADSL was still intermittent as of 3 Feb 2015. We have reported it 3 times since the 2 January 2015. Therefore the problem has not been resolved satisfactorily. Telkom has closed the query TWICE without resolution and then we have to open it again.. Why does it take this long to attend to a business ADSL. The current fault ref is 662CRK250115. We want the query resolved, we want a credit for our line rental and ADSL data costs for the month of January 2015. I have escalated this twice on the website? no response. We tried calling but it's no wonder that they have large call volumes, after holding for more than 50 minutes I gave up. Telkom technicians have called and said they will attend to this but we have never had a call back stating the result. We are using Vodacom wireless to connect and it is currently costing us a fortune to keep our business running. Where is Telkom? where are their technicians?
