Vodacom upgrades are a **** ( Deals i qualify for)

I have 4 contracts with vodacom with one being the "Red VIP" contract, 2 standard and a fibre contract, i have been a contract client for the last 19 years, i have tried to upgrade 2 of my contracts online just to find out that they now choose what you qualify for, so none of the fancy deals advertised online are for upgrades and the system does not allow you to go any further, to add insult to injury i called the customer contact centre to advise them to cancel the first contract as they have nothing of worth i can upgrade to, i was told to give them 30 days notice on a contract that should have ended in July, i was further advised that the contract rerms are against the device and not the services so an actual 24 month contract never expires until you explicitly cancel it, yet there are no options to cancel or request cancelation on the vodacom app. Lets get back to the "deals i qualify for" i can get an iphone15 but on the worst possible package at R1000 a month but i do not qualify for lets say a samsung tablet at R300 a month......make it make sense. Vodacom are a bunch of ******* who think the public are just idiots. I will be canceling the remaining 3 contracts as they come to there "device" end date (it is not a fixed term contract as those have an expiration date and should not need 30days cancelation notice) and i will be reporting this matter in detail to ICASA as there is no fair treatment of customers being shown here.
