How long does it take to activate an installed line

It has been 8 days and I am still waiting to have my fibre activated. I have multiple reference numbers.Every time I call in or attempt to use the WhatsApp chat it takes hours for anyone to get back to me. I evantually get through and then I'm told the lookup address has failed and is sitting with the open serve brand manager. This has been going on since Friday last week. I am always told they will expedite the process. I work from home and I can't wait any longer. Please can someone get back to me in regards to this. Webafrica claims that it takes 7 days to install a line. This is just a simple activation of a line that has already been installed. It has already been over a week. Please can this be sorted out ASAP, or tell me it can't be done and I will go to another service provider. I'm sure they will get it right
