Credit Card Facility

I have had a terrible bad service experience with this bank. I have a credit card with this bank, and I used the credit card to buy a car from a dealership. I did this in 2 payments made via the Capitec banking app. The first payment was for R5000 which was done on Tuesday. The next day (Wednesday) I did another transfer for R86 950 to complete the vehicle purchase. Now if you do bank transfers via the app, it does not give you an option to choose whether you want to put this payment on straight or budget facility - and I thought I would phone the client care centre and request them to put these payments together on budget over 48 months. Indeed, I phone the client care centre with high hopes that I would be assisted. I was sent from pillar to post. I spoke to about 5 different Consultants, all of them told me it cannot be done - and the last Consultant told me only collections department can help me with my query. Indeed, I called the collections department, only to also be turned away and told it cannot be done. Who then is supposed to help me with this simple enquiry. I thought this was simple, but I was so wrong. I have never seen such a bad service in my life. They say they are there to make the client's life easier, but they are actually making it difficult by not assisting us we need assistance. Can somebody please assist me urgently with this simple problem...please...please...please! Can you also at least update the app to give us an option to choose whether the payment must be on straight or budget and over how many months. Currently, there is no such option on the app.
