Webafrica - Incorrect billing and poor service delivery

1) Extremely bad service during the installation. 2) Monthly billing does not correspond to the advertisment. They have advertised a package for R399 per month , but are billing at R599. The reason for this are changing all the time. Firtsly they stated that this offer is only for new clients and not for existing clients. They were not able to indicate where this is stated on the add. After they were not able to indicate this to me . they stated that at the time I signed up it was at different rates. Also not true as I send them the communication history stating that it was in fact advertised at R399. 3) There whatssapp platform is not were effective as I am being transferred time and time again without anyone being able to assist me.
