Vodacom messed my credit rating up!

I app**** for a contract with Vodacom online, and after many weeks of them not getting back to me, I was forced to constantly contact myself, once everything was confirmed, I was told I’d get a call to confirm address for delivery, of which I did not…. They vetted me so many times, to a point that the WiFi I app**** for was cancelled due to my credit score dropping! This is insane! As a credit vetting clerk, knowing the criterias and moves I made, to be declined based on a low score as a good payer, is not on!!!! Vodacom then tells me the contract was cancelled by customer, and me being the customer, did not cancel a thing! This unprofessionalism is now taking a toll on my life, and messed all plans up! I cancelled wifi for a better deal, and was declined based on Vodacoms incompetency. This is absolutely sickening, especially being someone who works from home!
