Please refund!

In the space of 2 weeks I have had 2 issues linked to multi choice, the first was Onair related and now it's Showmax related. The crust of the matter is that they (DSTV) share our details with these mentioned companies. when these companies call, especially the elderly (In this case my pensioner mom) they sell themselves off as DSTV. My pensioner mother had yet another call from an agent who talked about activating Showmax. I was present during this call and was assured that unless we use Showmax, we will NOT be charged. it'll just be there on standby. we asked this numerous times for clarification. Today, my mom is debited R99, we have Never accessed showmax linked to DSTV in any form. when i call DSTV they told me it's not them and to "live chat with Showmax as they are the debitors. there is no number to call them apperently. I tried "live chatting" to Showmax (which is in itself a tedious process) but they can't assist me because we don't have login details\ email linked to any Showmax account. So not only can we not get a refund but my mom is at risk of being debited every month for something she doesn't use???
