Short on order

Good day, I had placed an order with chicken licken 1 DR PIXLEY KASEME STREET, DURBAN, 4001. Contact number(s). (031) ********** at 10.22am spoke to wiseman, my order was 8 hotwings soul 6, rock my soul, rock my soul straight, hot wings snax, and LMT burger, at 10.29am I had called back to order 1 more hotwings soul 6 in total 9 this time I spoke to the manager. Delivery arrived 10.52am at reception - my error I should have checked the order and countered when the delivery guy was here but I trusted it would be all there, tip was R10 but i had given r54 as everyone gave 10% of their order. when I got back to my office and I was short 2 packs of hotwings soul 6 - im very disappointed I called back the store they advised they will call back took my number down, i was impatient so I called back and i was told it was checked and doubled checked and packed then i asked for the manager who advised it was packed in front of him, so were did the 2 go when I only received 7. im utterly disappointed in this service we will never order from this branch ever again. I have ordered for other people and I had to now bear the cost of refunding them money. if 9 was sent, and I got 7 clearly there is something wrong.
