Worst service I have ever experienced!

I contacted Mondo on 11 September 2020 to cancel my contract before the 14 days period expires and I was told a courier company will be in contact with me after 14 working days to collect the item. When I heard nothing I sent Mondo an e-mail on the 19th September 2020 advising them I have heard northing but no response, another e-mail was sent 24 September 2020 again no response. I then called Mondo 9 October 2020 very frustrated with the service delivery and advised them that I will not be paying for the contract as I have requested numerous times that I do not accept the contract. I was then told that my cellphone will be cut off should I not make payment and they will get someone to collect the item by 13 October 2020 in order for them to cancel the contract and the contract should be cancelled by the time payment is required. I am absolutely disgusted that people who have been a Vodacom customer for over 20 years are being treated this way.
