Appalled by the customer service

Vodacom customer service sucks!!! Every agent in store or online gives mw different information. I have specified that i needed to change ownership for my mum and my account. First i was told that i need to send an email with all the details, then i was told my mum or myself would need to send a letter which we did then i was told that we need to be in store together which again i specified that we live in different provinces and it is impossible to do so and that this is a urgent matter as i cannot have my mum pay for my account as she is old and she has other priorities. Its an inconvenience to be sending her the money every month when she doesn't understand the process.
