Change of ownership drama!

So many years ago, I got 2 additional contracts for my siblings. These have since ended and I transferred them to prepaid accounts over 2yrs ago. Trying to change the numbers' RICA details to their details and its a nightmare! We suddenly all have to consent to credit checks and provide stamped bank statements (at ridiculous costs) to change an ID number and address? What ******* is this? We were given credit transfer forms when there is no credit to transfer! We've been to vodacom 3 times and the list of required documentation changes everytime! Such nonsense!
