Cell C and Pep Store @The Reef Germiston

I bought CellC data at Pep Store @The Reef for R89 6 gig tried to load it 2 time it failed, I called customer care they also tried on their side but failed. I was then advised by the CellC consultant to go back to the shop and ask for a refund. Since I was next to the shop while on the call I entered the store and asked just that and putting my phone on speaker so that the consultant can explain to the shop assistant that the data is still active but unable to be loaded on my number. I spent an hour waiting for the issue to be resolved but unfortunately I couldn't be assisted with a refund or the data to be loaded on my phone.

I eventually decided to leave the store and left the unloaded data and my contact number, 30 minutes later I got a call from the shop assistant telling me that she found out that I have been sold data for a home connect Sim and to use that data I need to buy a home connect Sim for R60.

What I fail to understand is how come the teller did not explain that I'm being sold a home connect data and calling CellC customer service how come the consultant did not know or see from the service provider side that the data I bought is not for my Sim card. I do not have R60 to buy a home connect sim, I need a refund or data that I can use on my number
