Whole Foods complaint: Poor communication, training, and customer service

I attempted to shop at Whole foods tonight to purchase ground beef, chihippeas, wine, and vinegar. I waited in line for approx 7 minutes and was rung up by a sales clerk. I tried to enter my amazon prime discount at the end when I realized the prices advertised were very different than what was rung up and he re directed me to customer service and couldnt apply a prime discount.I didn’t realize he didnt charge me before standing in the customer service line. This was 2 different lines with significant wait lines and he failed to tell me that he hadnt really wrung me up intially.I left the store in tears and returned all up items due to the poor communications and service. I am a neighbor to this store and would like to promote the positives going forward but tonight made me feel like i store cant handle amazon prime discounts or decent lines.
