Worst customer service next to service providing

They have been consistant for the most part in 2020. 2021 came, I ways paying but couldn't get through make use of their service, fast foward and I cancelled but they still haven't given me a refund nor given me airtime for 5 months - I made numerous calls to them and was rudely promised they were gonna re-emburse me, instead when I call the phone literally gets cut off in the middle of our conversation bc the consultant is irritated.

I want my refund, so quick to take the debit orders but no service delivery and lacks professionalism & ethics 😡😡
