Terrible Customer Service

On 14 December there was a promotion being run to get R125 off R500 which was only valid for the day.<br> I purchased items to attain the discount but through the check-out process I didn't see the field to add the promotion code to get my discount and the purchase went through.<br> I contacted the call centre and I spoke to a consultant who assured me that she was going to do a manual credit for me. (didn't get a ref number). On the 21 December is called to follow-up on whether the credit was done and there was no sight of it.<br> I then proceed to email [Email Removed] on the 21 December and got no response after the automated message which mentioned that someone would get back to me in 24 HOURS. I sent an email again on the 23 December and still no response.<br> This is pathetic service on their part as I needed my query to be acknowledged and assisted with a credit.<br> I still have all the emails as well as the promotion email with promo code.
