Vodacom witholding fibre line

I just want to state how dissappointed i am with vodacom's services.

Firstly they said i need to give a months notice to cancel my fibre services to which they said i cant do 30days as i cancelled in the beginning /Middle january and they can only complete the notice end of February.

Secondly the internet was switched off at the end of february and up to today i am struggling with Vodacom to release my fibre line.

I tried to speak to a supervisor/manager to which i get told they dont have any on site and they will call me back and i am still waiting for them to phone me back
