People with disabilities not accommodated

I have been a contract telkom mobile customer for almost 4 years now and have been very happy with the service. I recently lost my sim card and when I got a new sim card and wanted to do a simple sim swap was told that I need to go to a telkom shop. I am unable to get to a telkom shop as I am in a battery operated wheelchair and currently don't have transport to take me to a telkom shop. The sim swap used to be available over the telephone but this service apparently does no longer exist. This means I now pay for a contract that is no longer available to me as I cannot get to a telkom shop. I personally think this should be addressed and people with disabilities should be accommodated. It is not as if am not willing to go to a shop but a matter of that I can't get there.
