- *****- Feedback left by buyer.Past 6 monthsVerified purchaseThis Item shows one in stock. After placing the order I received an email stating they don't actually have the part in stock and would need to order it from their vendor. they stated it would take 11-12 weeks for them to get the part. I opted for a refund which they promptly took care of. However it has been a week and they still say they have one in stock on their Ebay page. This is a lie, they show stock they don't have. Its dishonest / untrustworthy .Reply from: thunder-parts- Feedback replied by seller thunder-parts.- Feedback replied by seller thunder-parts.We always aim to provide the best experience for our customers. That’s why we informed you promptly about our stock situation and helped with the refund. The listing showed incorrect stock due to an update error in our inventory system, not intentional dishonesty. We apologize for the confusion and appreciate your understanding as we work to improve our service. Thank you for your feedback and for bringing this into our attention.
