Poor service

I have made 2 online purchases with the makro rcs credit card on the 28 of march 2023 payment was unsuccessful for both orders but money was deducted from credit card i didnt even receive notification only discovered when i was checking my payment history that money went out. I have called several times they transfer my call to machine service and they never pick up the call also went to Makro Crown Mines they called the RCS and we were told to send an email that didnt even respond to till today. I dont know how am i gonna get my money back .i am so irritated about this poor service .Hope they will make time in their busy schedules to check my emails
