What service can be used to combine technical support channels into one?

Question

Technical support

Good day. Now our service advises clients through the following communication channels:

1. Crisp chat
   
2. Telegram
   
3. VK
   
4. Internal ticket system
   
5. Mail
   

This greatly complicates quality control and is too confusing for the support itself. Are there any services that can solve the existing problem?

Thanks

Answer 1

Service now, and for the rest, write simple integrations (or take ready-made ones). If it's too bold, then look for analogues

Answer 2

Zendesk, the gold standard of support
