Can yo give sample of your work including the quality of the discussion and how fluent you are on the English language. I saw many services like this that only use bot telegram account that usually post words like Hi, Hello and other general chat that typically don't interact to each other. I join many group in telegram that has this kind of annoying chatter. Displaying your sample work here will really help you attract potential customer. I know that the demand on this service is very high because startup project usually fake there engagement during the initial stage.
Feel free to send me a message on my telegram and I'll send your all proofs you need.
