Maintenance on a Saturday!?

I went to Typo Tygervalley (South Africa) on Saturday, 16 January 2016, with my daughter to spend her vouchers that she has received for Christmas and her birthday. When we wanted to pay, I was told that we cannot redeem our vouchers due to Maintenance on the system. I was flabbergasted!! How can a company do maintenance on a Saturday morning and have nothing in place for their customers to redeem their vouchers with. I had to go home and come back some other day to fetch the products that she wanted. (I went back on the Monday and the lady that helped me was not very friendly. Not motivating me at all to support Typo ever again despite my daughters' love for Typo!)<br> <br> I phoned Typo HQ SA, I was told that the National Manager will phone me back, never happened. <br> <br> TYPO AU did try to help me via DM on FB, but nothing really came of it. <br> <br> The Store Manager of Typo Tygervalley phoned me, but she cannot address my issue. I was again told that the National Manager will contact me, never happened!!<br> <br> How is it possible, that a company can do maintenance on their systems every Sat mrg and not have anything in place to assist their customers in redeeming vouchers!!<br> <br> Terrible!!
