Nextra Teleservices — No response

My customer id is 6016188. I submit a router collection request on 1 october 2021 and nextra representative said that your router will be collected within 60 days but now on 31 january 2022, , no one contact me for router and refund.And when i call nextra customer care they even dont pickup my call and now even dont replying my emails.When i contact local nextra agent located at gagan vihar rohta road meerut, , that said that solve your isuue yourself by contacting customer care.
