MIGRATION

I really cant wait to finish my vodacom contratcs, My Contract is not due for upgrade or cancellation. I want to MIGRATE, from 20GB to Flexi 0. There NO migration fee, but I still need to pay 30k upfront fee, why?

I called customer care, retentions, Im snd from pillar to post, no one knows what Im talking about (what a joke) Im told I need to oay for cancellation,,,, IS DONT WANT TO CANCEL, I JUST WANT TO MIGRATE MIGRATE MIGRATE,,, at Vodacom you can migrate within your contract term or what??? And sometimes its asking for migration fee, but in this case, theres no migration fee, only an upfront,,, For what coz no one seems to know why the upfront

Or ill just stop paying my Vodacom account, then Ill surely get assistance, coz you will be calling non stop for ur money
