The Quarry Creak staff are some of the most professional cheerful and all around friendly staff I’ve ever had the pleasure of working with. I entered the store and was immediately greeted by the entire staff in unison credit def must go to the manager Daniella for having such a pleasant environment. My visit was one of annoyance simply because it was bill related however I never felt that way during the process. I wasn’t sure exactly what it wanted to do I just know I didn’t want to pay such a high bill anymore since my needs have changed. Daniella quickly and efficiently became the perfect go between for myself and customer service which I hate dealing with. She was able to clearly instruct the rep on my needs even if I wasn’t. 10/10 highly recommended for any wireless needs. I’ll be back for purchases in the future for sure. View on Google
