Woolworths Online Shockingly Poor Service

I placed an order for essential clothing items with Woolworths Online on the 06 May 2020. I received a confirmation of payment & a list of the purchased items was recorded against my Order Number. My order was not received in full & only delivered after the quoted delivery period. I queried this with the Courier Company contracted by Woolworths, who informed me that the package was sealed & contained a single item only. I have called the Woolworths Customer Care, as well as the Online Call Centre numbers daily & I have never come through to a Call Centre Agent - all this at my own expense. I have also sent numerous e-mails to "***" without receiving any responses. I am mindful of the delays that are being experienced by businesses in general, however, not receiving any feedback to the volume of enquiries that I have made about my order, is absolutely unacceptable & not what I would expect from a leading Retail Store such as Woolworths. I would appreciate it if this matter could be resolved soonest.
