Error acknowledged but not willing to take responsibility

Sold me a package that was never activated, i did not realise it until now because the amount to pay was exactly the same as the previous contract. this is about 5 months ago.

Levanea Naidoo (Mondo) confirms it was cancelled but the system does not show the reason for the cancellation, nor the agent who did it. so you can't hold anyone accountable.She sends you from pillar to post, trying to avoid dealing with queries.

She insists MTN must solve this, I spoke with MTN who indicated it was Mondo who did it and I need to speak to them, now how on earth will MTN know the reason that you Mondo can't provide?
