I was charged and the employee didn’t give me the item

I was charged and the employee didn’t give me the item. I didn’t realize until I was back home bc I had multiple items. I called the store 6 times, each call rung for a while and was disconnected. I called the in app support hotline and was told (after being disconnected from my first call attempt after waiting 30 mins) that they cannot do anything and I have to contact the store. How am I supposed to contact a store that doesn’t answer? Shame on you target for making normal people jump through hoops to get what is rightfully theirs. Your support needs improvement. I have the receipt number and everything. Just wish someone would help me
