Inconsiderate and not helpful

I ordered a phone online with Telkom.They delivered the phone. But did not deliver the sim card. I Called the call centre and I was told that the sim card probably got lost in transit. I was also told that I will need to go into a telkom store , buy a sim and let them do a sim swap. I honestly am very upset as I do not agree with this. I do not see why i need to take out of my personal time to go into a store. I placed an order online because of the convenience of not going into a store. Telkom is now taking there mess up and putting it onto my shoulders to sort out. This is really such an inconvenience to me and it is terrible service!!! I was not responsible for losing the sim card. Clearly Telkom needs some education in customer service. The right solution would be for Telkom to sort this miss out, and not push it on me!!!!!
