The manager of that store does not help customers and what he wants is for customers to spend money on other pieces that are not. For me, the position he has is a lot for why a person like that does not deserve such a position.

Friend, I feel sorry for your case, it's not complaining, what do you mean, the manager doesn't help, I imagine that he tries to sell his merchandise, that's why the owner pays him, it's not about customers spending more, I've been looking for parts and they offer the most expensive of this, it's about supply and demand, if it didn't work for you, go somewhere else let's live in peace and harmony let's leave the complaints and formalities for another time we live in this beautiful country where freedom is unique and the rights of customers are respected have a nice afternoon blessings to all amen

What a pity that someone like that touches you, I have been lucky enough to run into people who have helped me

You have to see who your immediate superior is and make the complaint or look for a telephone number where you can make that complaint.
