Vodacom keeps cancelling my fiber sale and running credit checks against my name

I app**** for my Wi-Fi fiber 2 months back, it got approved, waited for installation until they came and installed.my internet was up and running I am happy. 2 weeks later Wi-Fi stopped working, when i contacted Vodacom fiber to my shock they said my sale has been cancelled. I must re apply at the sales department again of which I as I need the Wi-Fi. Sales department says i must contact the technical department to reconnect me, which I did, and I was reconnected a week in after being connected the Wi-Fi stops working again. I phone Vodacom, they say the Wi-Fi sale has been cancelled again. My biggest frustration is that every time i have t go through this process a credit check is done against my name which affects my credit score in a negative way. Right now, I am sitting with a router fiber that is not working because my sale has been cancelled again.
