Extremely bad experience at Afrihost

I had requested two devices by mistake when I initially got my contract, however I was able to return the other device without opening it. Problem is these two devices(including the one cancelled) still appear on my app and non has description telling me which one is cancelled. When my data ran out, I then needed to topup however I topped up on the incorrect device. I spoke to a consultant on whatsapp who advised that the money would be credited to my account as they cannot move data from one device to another. I waited and on the third day(today) I inquired seeing that nothing was being credited only to be told that I am not going to get my money because data is a Telkom issue. Fact is 1. It is Afriost responsibility to remove the cancelled device from my account. 2. I do not have a contract with Telkom but Afrihost. Why should I be pernalised for Afrihost's incompetency?
