DSTV overcharge Lusanad Vezi(DSTV Chat agent) not helpful

On the evening of 13/12/2022 I signed up for DSTV Stream (Compact Plus) for R469 and was quoted R187.60 to pay until 24/12/2022. I accepted this and paid R190. Today I logged into my DSTV account and saw I am being billed for the same product twice. I then contacted DSTV and spoke to Priscilla. she logged the call to reverse one (ref: #INC-***) was given and she said I must wait 3 Hours. 3 Hours later I logged back in and found that the package was cancelled but only R171.97 were refunded. I chat again, this time with LUSANDA VEZI which i refer to as the rude unhelpful one. She insists I bought two of the same packages yesterday and cancelled the one today. i explained my situation, that I only bought one so if there were 2 added then it was a system error. I asked her to reverse the further R15.63 which would make the total of R187.60 and she refused, insisted I bought 2 of the same thing yesterday. I asked to speak to a team leader and she kept saying she resolved my query, ignoring my continuous request to get the name and surname of her team leader.

DSTV must refund my R15.63, that is a lot of money to me.

Lusanda Vezi is a rude agent who do not have the capacity to work with paying customers, I want our conversation to be read and addressed
