Tikona — Harassment for device with none send to collect

Address:

Tikona subscription details Account no. 132145129

Tikona broadband is constantly sending mails to return their device to which I had several times written to them to send in their representatives to collect it. But none was sent and now they sending notices from Legacolls may be some legal firms.
I request you to please intervene and help to resolve the stalemate.
