Horrible service. No assistance at all!!!

I am so upset and dissappointed with @CapitecBankSA. I wanted to do an online purchase. So i set my limit to the amount of my purchase. However it kept on declining the purchase. When i texted capitec on whatsapp.The lady i get(Palesa)sends me an auto message on how to update my Limits I explain to her again my issue. She goes to my App and comes back to me saying i need to make a cash purchase or use another bank as my card is not allowed to do online purchases. I was charged over and over again for exceeding my limit where as this was the first online purchase i did today. Im extremely upset, what poor service, how do you tell a client to go use another bank? Capitec is my only bank. So basically you guys and your teams are saying i cant be helped.
