Useless call centre

good day

I have had a contract with a specific number with vodacom a few years ago and I would like to now transfer that number onto my wife's name for her to take out a new contract on her name, as simple as that sounds your call centre has zero knowledge on how this process works.. I have been asked to call *** vodacom accounts and the call keeps getting dropped and when I call ***4 to notify them they attempt to transfer my call which gets dropped aswell..i have called your call centre over five times and nobody could help me considering that we are still willing to support you with the lack of help being provided .. So can anybody help me in taking out a new contract and transferring this number or should we just consider moving over to another network that could possibly be more helpful. I will rate the service I received a -10

Thank you
