RUDE, CONDESCENDING AND BELITTLING ATTITUDE

So we made a fridge purchase last year at Game Store Gateway. The Samsung sales consultant went out of his way to explain the process to redeem the voucher. The sales consultant went as far as doing the redemption on our behalf. So last week we wanted to book a holiday using our voucher.The form was emailed and we completed the form and sent it back yesterday. Today we are told our voucher expires tomorrow the 14th Nov 2018 and Samsung needs 10 days to complete some admin for them to send a sms as confirmation. The consultant attending the call was rather rude and condescending , belittling, " logically "in her words if my voucher expires on the 14th November 2018 .How do I know Samsung requires 10 days to process my request. In my logic expiry is the 14th Nov 2018 and since we are still on the 13th November I think Samsung needs to process the admin with hast as the voucher is in still force. Your admin takes 10days. Your t's & c"s should be stipulate that booking should be made 10days prior to expiration date Samsung please rectify the matter and address it with your rude team. Honour our voucher so I can continue to be a valued customer .
