Bajaj Electricals — electric bread toaster malfunctioning

Address:

Kolkata, West Bengal, 700095

Hello,
I had bought a electrical toaster from spencers kolkata and it started mal-functioning after few months. After i lodged a complaint at customer care, company took my toaster and returned it back claiming that they have fixed the issue. However, the issues still persisted and i took it to again at service center located at prince anwar shah road connector, kolkata. It kept it their for 4 days without doing anything and when i asked to return it back to my home, the delivery boy started making blunt false excuses and behaved rudely with us. Even the lady sitting at the said service center did not bother to cooperate with us.
Is this the level of service that you provide to your customer???
I need a full refund of my product.
Thanks,
Jaydeep
