Order to be delivered

Good day Order issues

I need assistance please this is my second bad encounter within 6weeks, purchased on Monday and all was confirmed on Tuesday I got a text that driver is on route, around 5pm I texted him to inform him that for delivery purposes people are available from 8-4pm Monday - Friday, wherein he called me to inform me that he doesn't have my parcel however same Tuesday I got a massage to say Sorry we couldn't reach you for delivery you delivery will be scheduled and when I checked on the tracking app it was closed and indicated that my parcel has been taken back to the store, I sent an email to customer care but unfortunately the reply said they have a pile of emails therefore my problem could take time to be sorted and this morning I tried the chat app after I sent my story the app was blocked each time I tried typing it directed me to "send massage" now my problem is this situation is an inconvenience to me as I have ordered a pack of baby wipes which they are an essential and also with my first encounter I have to go and spend money on nappies as I had waited 7 days for my order until I contacted the call center, I buy on the app as it is convenient for me and it needs no moving around, and the main issue is that once products have been shipped out one cannot cancel the order, I honestly need assistance on my parcel please

Kind regards
