Telkom does not answer their phones

I have a business and Telkom is my supplier. I have their switchboard and and adsl line together with three other lines.<br> For the past months we have been experiencing serious internet problems. Telkom accuses Mweb and MWEb accuses Telkom. Every day we have to phone in and have Telkom reset the port. The Telkom technician advised us to have one of our lines changes to a dedicated data line and then have Mweb allocate the adsl line to this line.<br> No Problem but how do I do this. For two days now I have been trying in vain to contact Telkoms business section. Nothing No One answers the phone. I go onto their web site there are no contact numbers. How is it that the biggest land line provider does not answer its phone. How must I fix this problem?????
