Vodacom Poor service delivery

I had a my Fibre line Installed over a month ago, which Vodacom linked to my Cellphone account. This created a problem with the credit limit on my cellphone account. My cell phone line keeps being suspended due to the credit limit. I have been calling Vodacom on a number of occasions to resolve this problem, but no one at Vodacom has taken ownership of my query to help and resolve this problem.
