Pathetic Cell C after service

Well I was contacted by Cell C to supply me with fibre to my residence. After being contacted a few time via e-mail I decided to sign up with then regarding the viber to my house. I was told with in 4-6 weeks my fibre will be installed and working. The router was delivered within 3 days after I made a payment on my new account. At the end of May a payment was deducted from my bank account.. Now 6 weeks after the first payment was made I decided to call Cell C to inquire about the installation, well that was a waste of time as they put me on hold for almost 2 hours. I then diverted to writing a email to the lady that assisted me to find out when Open Serve will make contact with me, she still needs to reply my mail. I then sent a email to the person that was dealing with my installation from cell C side and he told me that Open Serve said that I already have a device installed at my house, which I don't. He said that he will esculate with them and come back to me. He sent me a email telling me that he have esculated with Opens Serve.... I have since then not heart from him again after asking if I need to wait a further 4-6 weeks. I think this is bad service to a client that have 2 other accounts with them as well.. I would love to hear what they explanation would be next.
