Frustrating and inconvenienced by Rain

I took a package with rain in December where i specifically asked to pay R625 a month on 30mbps speed package , and when i wanted to pay for my subscription on the 15 of Jan to my surprised I'm told that i took a 60mbps speed package, i have been calling and sending messages through their AI assist so i can make payment but no success I've sent from pillar to post, it's been a rather frustrating and inconvenience exercise , if this is a way their Point of sale agents use to earn high commission , then it's a terrible way to use , if rain cannot resolve my issue we can rather cancel and i will find another service provider, it's all about Principles
