Mondo, you are making your customers feel helpless, feeling more like a victim of a **** than a customer

In short, I was blatantly **** to by Mondo's sales rep over the phone. He assured me I can keep my current number and the contract data & airtime added to my current number, after phoning Mondo multiple times and going to a MTN store 3 times, it turns out you cant transfer the data, the process was incorrectly handled by Mondo as per the assistant at the MTN store. So hence I returned the phone within 7 days to get the contract cancelled, DSV picked it up on the 7th of December 2022. I am still getting billed for a phone and sim that I have not had since the 7th of December 2022. I have been phoning & emailing Mondo to find out what is going on. No one gets back to me with an update since last year and I am still paying for a sim and phone I have allready sent back to Mondo last year December. If I phone Mondo, the call gets or dropped or you hold on for 10 minutes and get the same story "Mondo is waiting for a number from the MTN Wharehouse to prove that they received the phone" How long can it take for a phone to be shipped to a wharehouse in South Africa from within South Africa, it has been sent to the Wharehouse on the 7th of December allready. You cannot get any relevant information from anyone at Mondo and the story stays the same.....waiting for a number from the wharehouse to do the cancellation. Unfortunately it seems my only option now is to get legal advice and start the process from that angle, as it is impossible to get anyone at Mondo to get this matter sorted out. NOTE TO MONDO, I already have a reference number. Mondo, you are making your customers feel helpless and frustrated, feeling more like a victim of a **** than a customer.
