I have sent innumerable email reminders but i have not got response.
I have tried to contact over phone but i could not get any response.
The amounts i paid are stuck up.
'unlock 1 & 2 have been implemented. Unlock 3 is also being implemented.
Please note that the above agency is spoiling the greatest image & reputation m/s hp india pvt. Ltd. Has built up.
Please look into the matter & help me get my above two cartridges or refund of rs. 1, 512/76 that i paid online. With regards.
