I paid for a platinum AGM battery. The tech showed up late and without the proper tools. He caused some damage to the positive terminal. Then he produced a gold level lead acid battery and insisted it was correct. A text conversation with customer service established that the battery I ordered was apparently out of stock and they sent a lesser model. There was no notification of this before changing the order. Further, the cost for this battery was over $100.00 less than what I was charged and I have not been refunded. This was a terrible experience and I seem to be out over $100.00
