Poor customer service

I've been on a contract with Vodacom for 10 years. I wanted to migrate my package from a TopUp to an open contract to make use of an eSIM. I am told, once the migrate quote has been generated, that I must pay R3000 in penalty fees? This is absolutely ridiculous I am also told that the quote cannot be change but yet it went from R3000 to R2100 since yesterday? At this point it would be cheaper for me to prematurely cancel the contract and take out a new one? This makes absolutely no sense. The people on the help line refuse to escalate the situation. I have never missed a payment for the contract in all the years I have been with Vodacom. I expect better service than this. Will be cancelling my contract and moving over to MTN
