Keyboard is changed with a different one
On 19 July 12 I replaced my hp pavilion dv6-3153nr laptop keyboard product no- 606747-001 from redington India ltd, but they replaced this keyboard with dv5-407857-b31 as per the bill given to me. When I complaint about this thing they told me that it is the only keyboard coming with same product no and the bill is wrong and they will change my keyboard but after two weeks they told me my keyboard is not available and they will not give my money back. Please tell me what all actions can I take against them. As I am in defense forces I have other considerations also. Please give me some information on this matter.
