Just another Hellcom

I app**** for business wireless internet and VOIP line in January. I was told the installation would be done within two week. The installation was done only three weeks later. VOIP, I was told, would be delayed as I was porting my existing number from a previous service provider. Over a month later VOIP was still inactive so I requested a second line (a new one). It is now mid March and neither line is active. I have tried calling, but whoever I get through to is unable to help. I am transferred from department to department until I am originally transferred back to the original person I spoke to. I've tried emailing, but they seem to have an automated response that just says that due to technical reasons they cannot contact me. The lady who I had made the original application with, just says I must be patient.
