Aldo (South Africa): refuses to engage regarding missing order

Worst customer service ever experienced! I ordered 2 pairs of shoes online on 25 June. After not having received my order in some weeks I made contact via email and was constantly assured that my order will be prioritized. One of the two pairs was eventually delivered on 18 August. Upon inquiry regarding the second pair of shoes that I did not receive, Aldo claimed that it was delivered. I keep on requesting a response in regards to this, even sending a copy of the tax invoice that accompanied the sole delivered pair of shoes. The tax invoice has both products listed, and a hand-written note by the missing pair: "NB Order not for customer". It is 27 August - more than 2 months since I place the order - and Aldo refuses to make contact with me. I am amazed by how utterly nonchalant Aldo is in satisfying their customers, and blatantly refusing to solve reported issues.
