Business ProfileforElectric Zip

I ordered an ebike on June 22. I paid $709 for a 36 volt cruiser bike. When I had not recieved the bike, but HAD recieved shipping confirmation, I reached out to the company and was told by ***************** that they no longer had the bike I purchased in stock, but they'd send me the 24v version and refund me the difference between the 2 bikes ($130) I agreed to this. I recieved a refund for only $80, and when I looked at the website, they changed the price of the 24v bike to $50 more than it was originally! I had a screenshot from ****** of the web page with the original, unchanged price. I asked about the additional $50 refund I was owed and heard nothing. When I recieved my 24v ebike, I assembled it but noticed it wasn't shifting or braking correctly, and the power was cutting on and off. I took the bike to a repair shop to be looked over, and when they removed the plastic protector covering the shift cables, brake line and battery cable, they noticed all of the wires had been sliced through. They said it was not repairable and I should ask for replacement from the ElectricZip. I sent multiple emails and made multiple calls to both ***************** and ********* detailing the situation and did not hear anything back, so 5 days later I opened a dispute with my credit card company. That's when I recieved an email from ********* stating "we were going to give you a refund but the credit card company took our money". My dispute was denied. I then reached out to ********* and ****** again to ask if they would now refund me. I have not gotten any response, I have been reaching out since July. It is now November.
