Appsdaily — Samsung s7 edge plus

I have given my s7edge + ..with an amount of 3700 to apps daily and it's been 4 months I have not received my phone yet this is a big issue. They are not responding to my calls to their toll free number..i have purchased this handset for 54k .and it Was a huge amount for me to spend on a mobile.it is frustrating that a company like this do to its customers, and I took this platinum and they said they will replace it in 10 days it's now been more than 100 days.. I am really upset. I just want my mobile back.
