Vodacom Fibre Migration Fee even though we were told free to upgrade when we signed up

Absolutely appalled at Vodacom Fibre's service. It used to be a simple process to change your package, now its a whole procedure and a migration fee ( even though I was told at the time I signed up it was free to upgrade at any time ) All I want to do is change from a capped to an uncapped package and it will take a minimum of 2 weeks to a month to change apparently ! If that isn't bad enough they change their data packages but don't apply the change to their existing customers, so even though the package I signed up for was changed to 800gig ( 2 months after I signed up ) I only get 600gig even though they don't do a 600gig package anymore and the price I pay is more than they charge for the same 40/20 line with 800gig. Vodacom charges higher prices for their Fibre as it is and then delivers subpar service and rips the consumer off every chance they get. Don't get Vodacom Fibre, we had no choice as they were the only service provider in our estate but I would not recommend them to anyone !
