Wrong Package

I had called on July 14th about the incorrect package I have received, My call ref number J05778. They said they will look into and I should give 3 - 4 working days, it passed. I called again close to month end , 2 weeks later to ask about the progress they said they are swamped because of the lockdown but they are still looking into. I think I have been patient enough with them. I'm not happy with the package I received, I need feedback so they can cancel the contract and I can get a new one. The reason for the investigation is to see who was wrong and to see who will pay the cancellation fee. I know I wasn't wrong and I know the package I was offered is 40 gig ( 20 anytime data and 20 nightsurfer data) but instead I got 15 ( 10 anytime and 5 nightsurfer) not what was agreed on with the sales consultant I spoke with on my *** number. Please deal with quickly coz I don't want to pay another installment on something I'm not happy with.
