Problem with Sears Customer Service and Policy

On Feb 13th, I purchased boots through Sears.ca and received an e-mail confirming my pick up date for Feb 16th. Sears.ca has a promise date of 2-3 business days for delivery. To make a long story short, the boots never arrived. Between Feb 19th to Feb 23rd, I called the customer service at 1-800-267-3277 and the corporate customer service at 1-800-664-1888 about 4 times to find out the status of the delivery. It was supposed to be delivered to a Sears catalogue agency (the local dry cleaners). The first 3 times I was told the boots were placed on the truck on Feb 14th and was probably delayed by the Family Day holiday on Feb 18 (but my promised pick up date was Feb 16), and should arrive, call back if it doesn't. I was told to call the corporate service number because I wanted a tracking number for the order. At this number I am told the same thing, so I ask to speak to a supervisor, and am told that all service reps at the corporate number were supervisors, so there is no one to escalate my call to. There is no tracking number, but a truck was expected to make deliveries at my pick up location the next day, so it must be on the truck and should arrive, call back if it doesn't. The boots never arrived and on Feb 23, my wife called corporate customer service again and is told right away - the boots should have arrived by now, regardless of the holiday and they must be lost. She will re-order the boots and will credit the Sears account for the first pair of boots and will send a $10 card. We received the boots the next week, all was fine until I received my Sears card statement the very next day - I was charged for the first pair of boots. I call the Sears card customer service and I am told that there are 2 charges for the boots on my card, and no credit and I should call the catalogue service line. My wife calls the corporate customer service line again. She is told that the credit is not applied until 30 days after the order. My wife asks if I will be charged interest, because my Sears card shows over $100 owing this month for the missing boots, which I will not pay, but the credit will not be applied until the next statement. The Sears corporate service rep doesn't know, but just call back if it does and they will reverse the charges. My wife tells her that we are fed up with wasting our time calling Sears. Corporate customer service makes a notation in their system so that Sears credit card services will credit the amount for the missing boots, but they can't make a notation to credit for any accrued interest due to their policy of delaying the credit? If I hadn't called 4 times already to clear up the mess with the boots, I wouldn't be as upset, but now I have to call again, in case they make a mistake and charge me interest. Apparently Sears will charge you on the date you make an on-line purchase, whether you receive it or not (which they would know, because in order to pick up the item, you must show your Sears card and sign for the package), but in order to credit the charges for the item you haven't received, their policy is 30 days. My wife tells the service rep that this policy is awful and her reply is that's your opinion and they are sending us $10! The boots are great, but not worth this aggravation and $10. I will return the boots to Sears and spend my money elsewhere. I was told that I could contact a Dean Rogers at their National Customer Service Centre. I figure I will probably just get the same answer from him "it's Sears policy", so I think I will be better served by posting my complaint here.
