Appalling Service delivery! So So BAD

The complete lack of service from this provider is absolutely astounding!!!! I received an unsolicited call from them in June 2021 stating they were from Mondo on behalf of MTN and offering me an "upgrade" to an existing data contract. This was not the truth as I discovered when the new router was delivered, they had opened a new contract for me and not an upgrade. On top of this the router and sim sent were not compatible and could not function. I contacted them first on July 6th to request the contract be cancelled after going to my local MTN store to request the same and being referred to Mondo directly. Since then I have emailed, called and sent the router and sim back via their MTN courier, which I have proof of and ref nrs for. I was debited for the service which I had no way of using and a refund was promised during the many emails and calls. To date this has not happened and I have had not a word of feedback or apology from either MTN or Mondo. STAY AWAY these people are con artists at best!
