Non-Existent Customer Service

I have been trying to place an order online since the 6th of March but am unable to complete the checkout process. On the 8th of March i contacted Customer Services to assist since i had a voucher that would expire on the 11th - I have sent screenshots of my order and asked numerous times for my order to be processed manually (less R200 discount for expired voucher)- I am still waiting for my order to arrive / any feedback on this issue.....I have in the meantime sent 2 emails to ********** neither of which has received any reply except an automated response. Surely a dedicated complaints email should endeavour to reply to each complaint within a maximum time of 24hrs?! What a pathetic excuse for customer service! It has been almost a month since I first tried to place this order.... How can it take this long to process an order and ship it to me?!
