Horrific customer service after sandals sole broke in two

The service at the Vanderbijlpark (DF Malan street) is absolutely terrible. First of all. I bought sandals on 12 Feb 2024- do the maths. The sole broke in two. Who keeps a receipt if you decided to keep the item you purchased? Well. they expect you too. I also the SMS they send, will be deleted, no doubt.

I took a screenshot of my banking app with the purchase proof date and amount. I also had the BOX I purchased the sandals in. They were unable to assist. First because of the slip, then the item had to be EXCHANGED. Why? I did not find something suitable and requested a voucher - NOT CASH. Then the excuse was that they are offline and cannot process anything.

I left. Please help, as their email address and phone number is also a dead end
