Regarding a damn weird paypal issue !

Hi,
I have a 5 years old paypal verified business account , smooth history and no problem so far with paypal .
The problem is when I use this old paypal for receiving payment , my script didn't send goods automatically to our customers as it should be .
I thought it's due to our script , so I asked developer to check but nothing wrong . Then I tried many different paypal accounts to receive payments and script work perfectly , all stuffs sent to our customers without any problem so far automatically .
I thought it's due to my country , so I tried to use a same country but different paypal account and script worked perfectly again automatically . Finally I tried again with my paypal and fuck , the issue back , script didn't send anything to my customer after purchased .....so weird
Then I tried to register a new paypal and this new paypal work perfectly just as others paypal ..
Anybody have any idea about what the hell is this shit ? I'm confused ....trying to contact paypal , not sure if they respond back
Thank you for your reading ! I'm appreciated for your help
Best Regards

Paypal always having issues, that's why everybody looking alternative payment options. It's not a good idea to use only paypal, you should check other payment options because you are losing potential customers.

Give them a call,its the fastest way to contact them.

if you have emailed them, then they generally respond in 7-10 days.
