Not connecting fibre

Openserve installed fibre in our area Protea Valley, Bellville, After completion of installation we app**** with ISP Telkom and signed fibre contract. Three months later and Telkom can still not finalise the installation since Openserve did not finalise our house fibre line at the exchange server. Area is live according to both Telkom and Openserve. Openserve provide automated answers to queries and does not investigate and solve the problem as per request from me and Telkom
