Hi In short, the refund/exchange business of the mambo 5 etc worked out. The guy that didnt want to refund me the money unless i baught another trumpet of them, was not in the shop on sunday. He left a letter for the workers on how to refund my money and they apparantely read the letter wrong and gave me the money without buying something else. I was very happy about that because after i tried the VBS1 silver plate bach next to the stomvi Mambo 5 that i was going to have to give back, i was disgusted. The bach vbs1 (to me ofcourse) is a horrible sounding instrument compare to the stomvi mambo 5. It also feels like plastic in comparrison to the mambo. Mambo is definately a much higher quality build than the bach VBS1. So im happy i did not have to buy the bach and got my refund instead (simply because the workers read the letter wrong and thought it said i can get refund without buying).
