Have not fixed ADSL

Telkom tested my restaurants ADSL line on Monday and said they would send a technician out as soon as possible to fix the problem. By Tuesday no one had contacted me, so I called the technician and he said he was just finishing a job and would be there shortly. Wednesday still nothing, so I phoned telkom again and they said it was still in waiting period. The lady that I spoke to was very short and rude to me. Today I phoned again and waited for almost an hour for them to tell me again that they will come out to fix the problem. Most my bookings for the restaurant are done on ADSL and I cannot afford for it to be down, especially seen as I am paying for the service!
