Please fix these critical issues in your app!!!

When Telephone contact is clicked, it opens windows select application option without offering any applications that may be used for direct phone calling, here however the potential customer cannot see the company phone number if he/she does not have the application to make landline calls with.

When Skype contact is clicked, it opens my Skype application, enables my webcam with the button to "Start call" being displayed at the bottom of the webcam display screen.

When Viber contact is clicked, it opens my Viber application and shows pop-up prompt advising: "Request Unavailable. The requested page is unavailable." where I click "OK" and nothing else happens.

When WhatsApp contact is clicked, the browser leaves the website and goes into a continuous page reload at https://web.whatsapp.com/send?phone=+44{numbers}

Does not work. Apparently after the install it will only point back to the download setting. Don't know if something is wrong or if this product has been discontinued.
