I hate shops like this

I dropped my rear end off Dec. 17th. The shop still has not done shi* to it. They told me it should take around 10days and now its 20. They tried to tell me that when they opened up the differential cover that all my spider gears were junk, and that if I put it in a truck that it would make sounds and end up breaking, not knowing that I had it in my daily driver. Then I told him that it hasnt ever made noise or gave me problems and he said "oh god I dont see how it didnt". Man shut the fuc* up idiots. Now the problem is that the delivery people are taking to long and that they keep tryin to track it but cant. Hello jackass it has been 20 days I can get axles from Jegs in about 4. I just hate shops who have sorry ass customer service, they can do the best work in the world but if customer service sucks then I believe you shouldnt get business. Speciality Metal Works in houston dont go there. Later.
