Shocking Vodacom Fibre service

We are with Vodacom Fibre using the Openserve infrastructure. We live in Kenton on Sea. Never have I experienced such poor, inefficient service and lack urgency. On Wed 3 April at 06h36 I logged a ticket with the Vodacom help desk #RS*** as our fibre internet service had stopped working. I work from home so this is a big issue for me. I have phoned them every day (up to 3 times a day) to get resolution but still no internet 12 days later (nearly 2 full weeks!). No one had bothered to phone me back, or keep me updated. Requested management contact me - I am still waiting. I managed to get hold of someone at Openserve who advised me there was nothing they could do as Vodacom had suspended the service and they needed to reapply. Still we wait - In the meantime we are having to buy very expensive cel phone data bundles in order to be able to keep working. What is Vodacom doing to resolve our situation … ! Our next step can only be to take legal advi*****t.
