Hi, Francis62, and welcome to the Community,
Here is a link to the instruction on how to contact Skype Customer Service via their secure portal: Contact Customer Service
Here are a few extra notes to help you find your way:
You will need to proceed through each step, one at a time. Sign on to the Skype website as requested. Choose the subject and topic which most closely matches the item you need assistance with. Then, continue past Step 2 of the instruction where several articles from the FAQ library will appear for you to review, and proceed to Step 3, Continue Support Request (the blue "button" appears at the lower right corner of the website page). You may also skip through Step 4 where you will be referred back here to the Community; no need to do this as the Community is where you started. When you complete the webform and click Submit, your information is relayed to Skype and you will receive a reply via e-mail.
If you are a Skype Premium or other eligible customer, you will be routed to start an instant message chat session with a Customer Service agent.
