No Customer Service at Makro

Makro Since May 2015 they are failing to sort out my payment I made in May 2015. I wasted my time more money trying to call them to sort out my account but till to date no solution instead they keep on sending SMS saying I must pay. I called Makro more than 20 times with different agent promise but can't deliver. The last time I use my account was March 2015 for 2200 and by early June 2015 my account was fully paid up and Makro is owing me instead but they still want me to pay. I am tied now of communicating with Makro they need to use their recording. As for me Not planning to ever visit the shop. And will not pay a cent any more. A shop this big takes more than 7' months to sort single account payment, now we on the eight month.
