Poor service

My query from April/March still can't be resolved. Was offered a special migration for one of my numbers. However, they migrated all 3 numbers, which meant from R690 a month had to pay R1300. Laid a complaint was advised that they will do an investigation, guess what? Still has not been resolved.

I received a call from Vodacom agent who confirmed that he will migrate my contract back to the normal package I started with.

I then asked when is one of my contracts matures and he advised that it is maturing this month. Should I wish to cancel, I should do it immediately before they invoice me for next month.

Called cancelation department can't cancel due to my account been frozen. Was request to call *** for assistance. However, the automated response states my account is up to date. Can I get assistance with cancelation please.
