Charged for items not delivered

Made online food purchase on 5/1/2021 to be delivered on 7/2/2021, delivery was made on the 8/1/2021, no apologies were made and 2 items were missing on the list, tried phoning the 0860 number which used R100 of my airtime while they played telemarketing messages instead of connecting me to an agent. Sent an email describing the non-comformance still waiting for a response, which would be unlikely as they don't respond.
