I ordered a QSC clutch kit. I never received a confirmation that my kit was shipped or on its way. I couldn't get ahold of QSC on the phone or by email. I thought they took the money and ran. I contacted paypal to dispute the purchase. My dispute woke them up and I finally got a shipping number. They apologized and said they've been busy. I have the clutch kit but was having issues removing the clutches and needed the proper tools. I called QSC with no answer again. I contacted EPI who answered immediately and helped answer all my questions and were very polite on the phone. They also guided me to a youtube site where they have videos on a clutch install. Awesome people over there at EPI. I'm sorry I purchased from QSC and had to get help from EPI. EPI has a new customer and I'll purchase from them here on out. Special thanks to Chad at EPI. Thank you so much!
