I bought an item from a UK company. The item failed after a few days and they insisted that I send this weighty item to Germany, at my own expense, for review. I had paid by PayPal and opened a dispute, later a claim. Despite the clear problem, PayPal changed the dispute to say that the item received was not as specified. I never said that, PayPal did. Then PayPal said that I had modified the item and I was therefore not entitled to a refund. Where they got that from, I don't know, but certainly not me. They closed the dispute and I was unable to answer this false accusation.
So I opened a second dispute. Again PayPal changed the nature of the dispute, saying that my complaint was because I had never authorised this purchase. I never said this and once again, PayPal closed the claim so I am completely unable to contact PayPal to find out why the nature of the dispute was changed, by them, to something that was untrue and was never said by me.
I have now checked various review sites and aas a result closede my PayPal account. It seems something pretty horrible is going on with them.
