Terrible service from Telkom business.

I am a general practitioner in Louis Trichardt, Limpopo. We have moved our premises on 8 January this year to a new property. We have been trying to get them to move our Telkom telephone lines since 12 December last year. During the past two weeks we have been emailing and phoning them almost daily to come and move the lines over, but we are still waiting. They promised yesterday that an agent would call us to arrange everything, but still nothing has happened! To top it all off, we have been battling for two years to try to change the ownership of these lines, and at this moment it is still in the previous Doctor's name! I am feeling totally helpless and very furious, because at this stage people can't reach us to make appointments and we can also not send our claims in to the medical aids, because we don't have internet! This is a huge loss for my business! Please help!
