No longer an option to use vouchers during payment

Your stupidity never fails to amaze me. I seem to log a hellopeter complaint every time I order from you and the experience becomes worse each time. <br> <br> I have 2 R100 vouchers which I wanted to redeem on 2 orders. In addition I also have a large amount of takealot credits.<br> <br> The imbeciles in your web design team have now automated payment if credits are owing and this has prevented me from using my vouchers. How stupid can you possibly be??? As I customer it is my right to decide how I want to pay. Who the **** gave you the right to decide for me????<br> <br> Kindly refund my store credit to my bank account or alternatively convert my vouchers to store credit as you have taken away my ability to use them. I want this done before 17h00 tomorrow!!!!<br> <br> You guys are seriously ****ing thick! I wish I had an alternative vendor to purchase from but sadly you bought out the competition!
