Daylight ******* by Vodacom

Vodacom is *****ing from me. My data contract expired in September 2023 and has been running on a month to month basis. For the past three months Vodacom decided to reduce the data I'm getting and streaming data without notifying me, however the subscription amount remained the same. Upon realizing this *******, I opted to cancel the contract March 2024 and got the confirmation that it will be cancelled effective 30 April 2024. On the 1st April 2024 Vodacom gave a mere 30 Gig instead of the 100 Gig i subscribed for and I'm still being charged the full subscription amount. What kind of ******* is this? Reducing benefits but the amount remaining the same. Surely you'll lose a customer as I won't renew the other contract I have with you.
