What must I do with someone else's groceries Makro?

3 March - I placed an order online 6 March - Someone else's groceries were delivered to my house while I was at work. Thankfully my kids did not open the boxes 7 - 8 March - I tried to reach Makro on their what's app line. I got a response that my issue has been escalated 9 March - I sent an email and got a response that my issue has been resolved. I called the call centre. The person helping said he would log a return 10 March - I got 2 emails *** said I must send 4 clear pictures otherwise they won't proceed. *** said they tried to call me. I must email all the details otherwise they can't proceed with the escalation.

In which world does one need to struggle to get a store come collect groceries they erroneously delivered to me?? They just don't care that there are two customers out there who have not received their groceries. This is madness.
