Timbl — Complaint against timbl

I have shifted my home from Faridabad to Delhi. I called timbl a lot before changing my house, then I used to call timbl again and again and ask them to shift wi-fi to my new house, but they just made new circles every day. Finally when timbl told me that we can't provide service in Delhi, I told timbl to take his router and charger and send my security money to my account, then he started making excuses and my router and did not take the charger. Rather tell me don't turn off wifi, give it to your relative or give it to a neighbor. Now I have shifted to Delhi, after that threatening messages have started coming from Timbl that give us our router and charger or else we will take legal action while I am repeatedly telling them that if you want to take back the router and charger so, please send your executive. I'll give you your stuff. But messages are coming from timbl but no official is coming.
