Quantity does not match delivery status

Good day I placed an order with you on the 2 des 2020,i received an email stating my parcel is with the couries,on the order with the curier it showed 6 items,upon receiving my parcel at work the way bill state 6 of 6.I only opened the parcel at home to find out there is only 3 items in the bag,i did notice it was very small but guess they know how to fold,the delivery ppl did not say i have to check my parcel before they leave,i will also not accept responsibility for this,as that parcel gets delivered in an office with other ppl,and has got nothing to do with them.also there is a second parcel still in processing,that only state that they cant find stock on those items,but do not update there site while placing an order,also no communication from there side why its still in processing,this is not the first time this has happened to me,they quick to take your order and money but cant deliver what you paid for, I need this to be noted because i will not pay for 6 items while only receiving 3 items. My order number is p*** Way bill number AAAA *** I suggest they do a stock count on there products and please send me the rest of my items .
