Unfair policies

So I purchased airtime for my new Telkom line to make an international call which is not catered for on my contract line only to realise its is not permitted on the my specific package. On trying to see what help Telkom can give in order not to lose out on the money spent on the airtime I was told in no uncertain terms that it is not possible. I must find someone to sell the airtime to. I'm not aware of anyone in my circles with a Telkom line so what Telkom wants me to do is go around randomly looking for someone to sell this voucher to. Since I dont have the time or energy to do so I lose out. Imagine how much money people are losing as a result of such policies which do not even accommodate error. Im not a random customer, I have two contracts with Telkom. Surely customers deserve to be accommodated in instances like these.
