Code 3 Locksmith

Bought my combo door lock in because was missing the key. Picked it up returned home installed it and it was didn’t work. Key didn’t work and worse yet the combo wouldn’t work either. Took it back the young man looked at it said no it worked. Took it back home and again key just wouldn’t lock the door and the combo wouldn’t work. I called and explained why it wouldn’t work and the man said do you want me to come over. I agreed because what else could I do. He showed up and couldn’t get it to work. I asked to please just get the combo to work again like it did before he broke it which after about a half hour and me helping him he got it t work. Now the fun part. He wanted a $ 60 trip charge and to charge me for a hour of his time. He never told me when he showed up what the trip charge would be and this was all their fault to begin with. I took a working lock in and now he wanted me to pay him another $ 100 on top of the $ 25 I paid to have the lock keyed!!! So I said no I’ll pay you the trip charge and no additional labor since I already paid $ 25. So paid $ 85 for them to break my lock and waste my time. They have no clue on fixing combo locks. I wish anyone good luck with this «lock Smith».
