I have been a Paypal and Paypal Credit customer for many years and have never had any problems and have always paid my payments on time. In XXXX 2016 I made a online purchase using Paypal Credit with the agreement that I had 6 months no payments and no interest expiring XXXX XXXX 2016. On or about the XX/XX/2016 I linked my XXXX XXXX XXXX XXXX savings account to my Paypal account ( via Paypal web site ) with the intent of paying that debt in full before the XXXX XXXX deadline, I was advised electronically that Paypal would be making XXXX small withdraws from that account within 2-3 days for confirmation before the account would become active and that I should review my XXXX XXXX XXXX statement for confirmation. After about a week I had not seen any withdraws from my XXXX XXXX account and contacted Paypal via telephone, their automated phone system is very difficult and confusing to navigate and took several attempts and several minutes to speak to a agent directly, after explaining to the agent that I had not yet received confirmation he checked my Paypal account and advised me that the XXXX XXXX savings account was confirmed, was active and I was good to go, I thanked him, hung up the phone and immediately scheduled a payment ( via my Paypal Credit account ) for the full amount, on XXXX XXXX 2016, from the XXXX XXXX XXXX XXXX XXXX account that is listed on my Paypal account, the scheduled payment appeared on my Paypal Credit account. 
Over the next couple weeks I made a couple small online purchases via Paypal using the above mentioned XXXX XXXX Savings account and received several emails from Paypal and XXXX XXXX that those payments were denied and as there was well more then enough funds to cover those payments as well as the scheduled payment on XXXX XXXX I contacted Paypal via phone again navigating thru their very confusing, frustrating automated phone system I made contact with an agent, after expressing my displeasure regarding their phone system I inquired as to the reason those payments were denied. After checking my account he explained to me that my bank ( XXXX XXXX ) does not allow electronic payments from savings accounts, I advised him that I accepted his explanation regarding XXXX XXXX but that I was very displeased with Paypal and expressed that displeasure very adamantly as I had payments being denied and a large payment scheduled for XXXX XXXX and Paypal advised me I could use that account, he further explained to me that those payments were made using another bank account listed on my Paypal account. I apologized, explaining that my displeasure was not with him rather with Paypal for giving me the go ahead to use that account and hung up. That night I logged on to my Paypal account to insure the payment for XXXX XXXX and quickly learned that my account was in a limited status, somehow while I was navigating thru their automated phone system I triggered a security feature, I phoned them again and was able to fix that. the next day approx. XXXX XXXX I phoned them again for the sole purpose of making sure the payment scheduled for XXXX XXXX was still on, they bounced me between agents and departments, I did as they instructed me and was under the impression that everything was fine, On XXXX XXXX I checked my bank account and the funds for that payment were still there, I phoned Paypal again and was advised no payment was scheduled and that I now owed {$310.00} in interest and fees, I paid the original loan and phoned their customer service the next day, I was advised there was nothing they could do, I asked to speak to a supervisor and was advised their supervisor does n't take phone calls, I asked review all phone calls regarding this matter, they said they would and replied via email that the would not waive finance charges and fees
