Mondo - Contact Difficulties

I received a call from Mondo, offering a "special offer" price on a Telkom 24 month data deal (including a portable router) with Mondo as middleman. When I asked for contact details to call them back, they refused to provide any, and I thus agreed to the deal preliminarily, as I have been interested in getting something like it.

After looking up the base Telkom deal, I found that Mondo wanted R40 of the R179 p/m (as well as a R99 admin fee) for the conveniences that they provide, which is a bit more than I was willing to pay. As such, I contacted them on the same day (yesterday, at time of posting) to indicate that I was cancelling the tentative agreement.

Their customer care line appears to be operating vastly over its capacity, with long wait times and no automated services beyond music and automated voice snippets. The first time I did reach a consultant, they seemingly dropped the call once they realised I wanted to make a cancellation, but the second consultant I reached proved helpful and sent through the cancellation.

Mondo's sales tactics appear to be rather anti-consumer, but I was fortunately able to reach an agreeable resolution with them on my fourth call to the customer care line, and after two unanswered emails.
