S8 screen replacement repair!

When my husband and I purchased our S8 and S8 Plus the consultant did not inform us that we needed to register with Samsung care service within 30 days of purchase - R69 per month - to cover screen repairs. No We find that we have to pay R5000 to replace one of the screens. After inquiring what options we have to become registered for this service we are told there is nothing that can be done and we have to pay the R5000!!! I find this unacceptable customer service as we were not informed that this service even existed. We were not even given the opportunity! How can you make us pay for your mistake? This goes against the customer protect act! I have always been a proud Samsung and Vodacom Paarl client but now I have a terrible taste in my mouth about this. I'm utterly disappointed and dissatisfied! I just can't believe Samsung would do this!
