One month and still no internet

A month ago Telkom came and installed a telephone line (there was a line already but they had to come and 'install' it). A few days later we had another company come and install our router. They got it connected and the Internet worked...intermittently so they called Telkom and asked if there was an issue. They said no, so the guy installing the router battled but couldn't get it going properly, he called again, and Telkom this time informed him that the line wasn't working properly and was slower than it should be, after this phone call the Internet stopped working altogether. He got an escalation number, and our case marked as 'urgent'. We received an SMS saying \your problem will be resolved within 48 hrs". A technician came 2 days later and concluded that there was an Earth on the underground line. He couldn't fix it but would transfer it on"
