Vodacom is nonsense

I have a problem with Vodacom even escalated the matter to my lawyers. I upgraded my phone in April early from iPhone 8 Plus to iPhone 13Pro so they were giving out bonus data bundles n I received an sms on the 24 August 2022 which I did not check as I was frustrated with work and I had just lost someone close to me, and I received an sms at 00:07 stating that the bonus data bundle dat I was getting has expired and if I want to opt out I must sms *135*140# which does not work bcoz every tym I try using it it says user not found. I then decided to call n I was told that they already billed me for the data, I don’t even need the data as I have a Data bundle sim dat gives me 400Gig day and 400Gig night every month with vodacom. I am angry bcoz the guy I spoke to over the phone wanted to make sure that he puts the blame on me for not checking the first sms which I was going through the most and vodacom sends a lot of sms’s u end up not reading all of them. My problem now is they have already billed me R170 something rand which I was not even aware of I am already paying 2000 for my phone I can’t pay extra 170 for something I had no control over as we are going through alot already. I hate Vodacom they have been giving me problems even now it’s still the same thing. I am changing my network their consultants have attitude n not even eager to help. They always charge you extra things without even communicating with you so why should I stick around I have been a loyal customer for over 10 years now n stl they frustrate me
