Misconduct from supplier

I have just been notified that Im not able to get any credit from supplier because there is misconduct on my credit account which I have to check with ITC. Only to find Vodacom has an outstanding account of my last bill after being a loyal customer for many years and not defaulting once. My last account was not accoding to Vodacom however my no. has been ported to Telkom which i have been using for over 5 months already. I even tried logging in to my account online to see my bill which you cant do, what good service!. Why should I call you customer care spend a hour on the phone and pay for it mind you to sort your mistake out.<br> Dont hate the competition rather let your customers go in peace please. How can you claim someone owes you money when you dont even notify that person firstly let alone if the money is being owed.
