Poor service from Telkom

I have been trying to do a sim swop on my eSIM and I paid R99 last week Saturday the 5th April and up to now the sim swop has not been effected. I went to the Telkom shop at Woodlands Boulevard in Pretoria yesterday and they told me there’s nothing they can do. I have 20 gigs of data which will be expiring at the end of this month if I don’t use it. I can’t use it because my sim swop is not done.
