Bad service from bottleshop.co.za

I placed an order on www.bottleshop.co.za on the 13th of October 2017. The website clearly stated a 24 - 48 hour delivery turnaround time on all orders. I did not receive feedback on delivery & by the 20th of OctoberI called the customer service number - The lady (Michelle) mentioned that there was a delay & that the order would be fulfilled by the 27th of October. I called on the 27th of October to confirm that I hadn't received my order, again only to be told that the order would now be fulfilled on Tuesday the 31st of October. Tuesday came & the order was still not fulfilled. I looked for the goods online & found another online store that would fulfil the order in 3 working days. I contact Bottleshop.co.za to cancel my order & the person on the line (a man this time) guided me on how to request a refund. I followed this process. On the 2nd of November I received email communication from Bottleshop.co.za stating that the order I cancelled was now with their courier company & the product would be delivered soon. I immediately tried calling on the customer care line it was engaged all 60 times I tried calling. I'm still trying to get a hold of them as I now have two of the same orders coming my way.
