Vodacom fibre Internet....what Internet??

Newly installed fibre line at our business isn't working. Not even a full month with vodacom and already issues. Reported the problem on the morning of tge 11th December 2020. Week later, no luck. Apology and promise to fix messages from vodacom, nothing yet.... Can't use computers, can't email attachments that's on systems, can't order stock, can't send customers info etc. Please CANCEL my fibre. I don't want anything further to do with vodacom. Im also not paying for the time Internet wasn't working. Come fetch your router and kindly get out of my life. I'll take my business somewhere else. Im not licking vodacoms backside a day longer. I have a business to run. 18 years im a loyal customer, this is how you treat me. No thanks. Smaller companies would appreciate the business. Goodbye.
