Wrong Item Delivered

I have never had an issue with any online orders placed with Zando, however this time I did, and are out of options to get my issues addressed.

On the 9th of July I ordered a pair of Utopia Shuffle Boots Navy, it was part of a promotion whereby I got 50% of the cheapest pair of boots. On the 12th of July I received a pair of Olive green Levi sneakers. I could not log a return because the item I purchased was not delivered. I phoned customer service on the 12th of July and got informed that their system is not currently working, I phoned back again later and got told to email the customer service department with photos of the item I received, the have to this day not responded to my email. I phoned the customer service again on the 15th of July and the return was logged, I was also informed that the discounted price will be refunded, (I have since bought the boots again at the higher price).

My issues are that my return is still not logged, nor did I get my refund, and I also feel that the full price should be refunded, as I am now being punished for Zando's mistake.
