Telkom left me without internet .

I signed up for LTE on 20/5/2015. I was informed the installation would take place in a day or two. Telkom advised I should give up my old adsl line by the end of the month,wich I did for the end of May. By the end of May the new installation had not even been done. Since then (I think on the second) they did the instalation but it never worked. Every day we phone Telkom, visit their shops, send sms's receive promises etc but now instead of having beter internet, we have no internet, no email etc. Our bussyiness is suffering. Our clients are disapounted. Boo Telkom!
