Reply for everyone's concern. One english speaking guy called and introduced him. He confirmed my name and office address. Than he handed over the phone to a bengali speaking guy so that I could tell him the office location. This guy was bithangedimmidiately the phone immidiately. After 5 minutes I called back to ask if they found the address and this time the english speaking guy asked if I was in office or not. I informed him that im on maternity leave. He congratulated me and asked about baby. Than he asked few questions about my company and my work. He also asked who would attend them in my absence. I assured them that my line manager is there to help.
After 12 minutes my line managers called me and said the conversation was over and he answered them properly. I dared not to ask him in detail. Thats all.
For your concern, I took help from visa center for ielts registration and it ruined me like hell. I received and replied pf on last years september.
Thanks.
