PayPal - Worst Service for Businesses

I have a subscription-based directory website where businesses sign up to get listed for $37.00 a year. I had a customer's directory subscription renew but who then - after 4+ months into the new subscription period - opened a PayPal buyer's dispute process saying they did not receive their merchandise - Case ID: PP-D-***8. The point being here is that there is NO physical merchandise involved but an intangible item in the form of a yearly subscription. So, I started down the road of having to provide my evidence to PayPal of the service (business listing) I was providing to the customer that they had signed up to. I sent a page document with my evidence to PayPal's Resolution Center; including dates, website URLs where the customer's business profile was listed. And so I waited... And I waited... I kept logging into PayPal to check the status of the dispute and still was under review. So I waited... I then received an email from Paypal stating "$37,00 USD has now been debited from your PayPal account for the following reason(s): We did not receive proof of fulfillment for intangible items." I not only had the money ($37.00) ****** from my account but they gave me a Chargeback charge on top of it! Trying to contact PayPal is the worst experience ever! I tried to contact them to dispute the refund but had to eventually go to their Facebook page and make a comment (among the thousands of unhappy customer comments) and eventually received a pat response saying they would escalate it to someone more experienced. And guess what? I never heard a thing. PayPal as a service is absolutely diabolical and their customer service is the pits. As a result I cancelled all of my business subscriptions with them and will be moving over to Payoneer.
