Not so express delivery

I made an online order on the 1st week of November and paid for express store delivery as i was soon to move out of town yet the order arrived a week after the original delivery date and for obvious reasons i could not collect it,i sent a dozen emails trying to communicate with customer care for assistance and a lady by the name of Asanda Gumeze promised to have it sorted out and refund me my money in a form of a voucher since i payed via EFT but six week's later I'm still waiting and she longer responds to my emails.I wonder if it would take you this long to call me if i was the one owing Mr Price. Talk about poor customer service
