Makro RCS messy

From Makro RCS I will rather stay away. Can you believe that it's impossible for me to pay them?? They can't help me. How is this possible, it should be smooth sailing. Besides that, my app doesn't work, and it's been a struggle for 7 months now (since the beginning). So how am I supposed to do sales with my Makro card online? What a mess. No one is able to sort this out. Looks like I'll have to close this account. Now it's been 2 weeks after I wrote this here, still nothing. Just escalating but nothing happens.
