The shoes I bought online is damaged.

Is this some sort of trick question or aptitude test? Anyway if yours is a real life scenario, 7 teachers will have to pay $6 each for 7 tickets which will equal $42 and summing that with the $2 each of 40 students which is $80 comes to a total cost of $122. That was not rocket science was it?

There are a few ways of handling this, either you can open up a package immediately and check for damages so that you can give the package back to the delivery service so that they may contact the seller on the matter, or you can go contact the company responsible for selling the merchandise, these contact infos are usually present in the website or fan page, they usually take it back and provide you with another model but it will probably take some time to do so

The use of the word “accidentally” ]which is always a fun word for lawyers. It’s possible, if the amount were great enough and the company decided to sue you over it, that if the situation were truly an accident, and not a negligent or reckless act, that a court would find no liability, this is because tort law is predicated on intent, generally speaking. Even negligence requires more than a mere “accident” — it requires a duty, a breach of that duty, and damages.

Since it was the store's fault, they have to give back a refund or give the missing items. They violated a law which is being honest to the customer. They did not even inform the customer that the product is not available nor give back the money as a refund. If they still did not reply or accommodate you, you can file a case because of fraudulent.

You have to contact the store to let them know that you want a refund. Give what documents or proofs that they are looking for. Next is to provide your credit card details, then sign the required documents. After it is settled, the refund may take five working days, depending on the terms and conditions of the bank.

Since the store is not giving any refund although it was their fault, you can report it to the local trading standards department because it was part of a statutory right of a customer. You can send them an email and notify the shop about what you are about to do. That way, maybe they will do something about your ordered products.
