Most unprofessional business i have ever dealt with

Most unprofessional business i have ever came across in my life. I contacted them and they told me the blank gun will be there on Saturday i spend money on uber going to the shop I get there the guy Warren told me he forgot the blank gun in Kempton park he then told me he will courier it on monday i must pick it up on monday he will make sure its there on mondsy. Monday comes they never call me to say blank gun arrived i called them they never answered. On tuesday i call them they said blank gun at the store i can fetch it between 12:00-13:00 i get a the store at 12:15 they just have a letter on the door to say closed for December after they confirmed i can come between 12:00 and 13:00 i left work used my uber money and they just dont care. I call warden they said they left already not going to come back after they wasted my time money and got my hopes up this was suppose to be a gift. Worse company ive ever dealt with and they simply dont care
