New Automotive AC Compressor with Clutch Sanden 4901 TRSE07 Style

I bought this compressor because of the brand name (Sanden) but when the item arrived it was a different brand (Omega). I asked the seller, and their response was the item is a Sanden style but not the actual Sanden compressor. The product name and description was misleading. My husband said that’s fine. We already waited for 5 days and the ac for the car has to be fixed so that our son can use it.Our mechanic installed it the following day and he said it did not work because the item was defective. It had caused more damage to our son’s car. Now the drier, expansion valves, tubing lines and cabin filter has to be replaced and plus the oil and refrigerant that were all wasted for nothing. We were trying to save money that’s why we bought our own parts and now we ended up paying for more. I am returning the item tomorrow.
