VODACOM Bad service

I did an upgrade on two numbers during February 2024. Only today 9 April 2024 did I receive confirmation that he upgrade is done. In the meantime I received various calls from Vodacom asking me if I want to upgrade. I also requested that an upgrade on a data line be cancelled and the service request was logged the same day as what the upgrades was done. Just to find out today that the data line is still active and nothing was done as requested in the service request. Also no feedback is given by Vodacom with regards to service requests. Is this how clients of 30 years plus os treated?
