Greedy sales agent misleading customers

I have spoken to a lady from innovation group sales - Standard bank Warranty department.

I asked her at the beginning of the call before the sale if I can get a top up or booster cover and she agreed that she'll put me through. Greedy for the sale she signed me up and then at the end of the call I asked her to transfer me to the top up dept and she advised me that I don't qualify for the top up and they won't be able to assist me.

I have the call recording. This is rude and terrible.

Ive been a customer to the ABSA warranty and is still showing your company support yet you guys are doing me wrong!
