Non delivery

23 June 2015 received personalised email with promotion on optic fibre. I accepted on 24 June. Call centre agent said she will phone me back. I made her aware of the special offer ending 30 June. She did not phone back as promised. Spoke to manager on morning of 1 July. Promised he will take up with her manager and call me. I have been following up in the meantime with no luck. Nobody can explain to me what the next step is. I was hooked with the special offer and due to poor service from Telkom I am losing out on the special and nobody can give me answers now. Please assist. Thank you
