ShopKo Internet Order Never Arrived Customer Service useless even tho UPS admits item likely lost internet

 Placed an order for a furinature item. UPS delviery date was scheduled for 3/14/2014. Item tracking has been stuck since 3/11 in IN. UPS states package most likely lost and that retailer should contact them to start a delivery trace. Reached out to ShopKO CS that UPS indicates they should initiate a trace supervisor states they cannot do that until full 10 business days after ship date, they indicate that the results of the trace will take 10-14 business days on top of the full 10 business days. I advise that will cause intrest charges to incur on my purchase and why should I be reponsible for that when it is their responsibility to initiate the trace that UPS says to do so. Rep kept quoting their policys, had to initiate dispute charges so they can deal with my credit card as i am not going to waste my time bickering with such an open and shut lost item case even UPS already admits it has lost. Talk about a supervisor/company not wanting to do thei basicis of their job.
