Mondo doing their best to stuff up

I ordered a mobile router from Mondo. Instead I received a home router from them. I returned the device on the 09 March 2023. I phoned them on the same day with the reference number to confirm that the courier has collected the device. On the 22nd March, I phoned again as I received my statement from Mtn telling me that I am being debited for the device I returned. The Mondo agent informed me that they are waiting for the Mtn Warehouse to inform them that they have received the device so that they can proceed with the cancelation process. They informed me it could take up to 10 working days. I have now phoned them again on the 26th April 2023 and they still have not received any correspondence from the Mtn warehouse that the device has been returned and no follow up from Mondo has been made to the Mtn warehouse. It has taken 2 months and still no progress on this matter. Feel free to contact me as I have spent a lot of airtime, phoning Mondo, who do not have a customer toll free number, so that this can get sorted. As far as I am concerned, the agent who offered me the package, did not listen to my request in the beginning as I told him on numerous occasions that I want a mobile router but instead was sent a home router. I specifically said that I do not need a home router as I have WiFi at home. I feel that this agent just wanted to close a deal no matter the request and that is extremely unprofessional. I will never recommend Mondo to anybody as you spend more money on handling incorrect orders that actually enjoying the product that was initially requested. Call me
