Parcel Lost

I ordered and paid for a few items on 25 Apr 2020. I understand that with some of the items there was a delay. I was supposed to receive the goods on Friday 8 May however due to an address issue the delivery was rescheduled. My question is if you can't find the client, why not call the client to confirm my address. The delivery was rescheduled for yesterday Mon 11 May 2020, again the delivery was rescheduled due to the address not available. I did not receive any call whatsoever. Today my parcel is lost in transit. Yet the delivery will be rescheduled.

I need the printer cartridges to print my daughter's school work exercises.

I am disappointed with the level of service.
