Fibre installed… Vodacom ISP can’t get my line activated.

Very poor communication. Being my ISP, they need to work with the fibre network provider to ensure that once my service is installed, it is activated. Installation complete but no activation of fibre line. I can’t contact Openserve directly because I must work through ISP. I call vodacom, I get no help. They say they will call be back after they follow up with Openserve, they don’t call back. Facebook and Twitter DMs, they say their technical team to provide feedback… I follow up, nothing… big tech company, my “small” problem. Highly disappointed.
