Hi,
-- NOW--
From description, It looks like you are facing some bug in your automation program, which uses twilio.
Let me know more details in chat.
I have 5+ years experience in web application development. I have mostly worked with Asp.net Core, Asp.net MVC 5, Web API, MS SQL Server, including frontend and backend both parts. I have done many third party integrations like TransUnion, Google Maps, Stripe Payments, Velocify, RigCentral etc. From last two years i am working on projects using AngularJS, Angular 4+ and React based front end technologies with backend technology as asp.net core API and NodeJS.
Thanks,
Siddharth S Mishra
