Samsung Mobile — S 5 MOBILE in service centre since 16/9

Address:

New Delhi, Delhi

I have given Samsung S5 since 16/9/15 for service. Phone is in warranty period.Since then I am getting harassed by samsung service centre & call centre. Sent an email to Ceo office regarding the matter, I was informed by service centre that my problem is not getting resolved & I will get refund. So cancelled check & Id was taken from me saying that I will get refund. Today I was called from head office saying that sir give us 2 days. We will inform u after that what will be solution or will escalate. This fraud company is harrasing me. Multiple time I have visited service centre & called all the possible number. After 25 days still they are not sure. Don't know what sort of company samsung is running
