Consumer Redressal

SAMSUNG have disinstalled and reinstalled my split air conditioner in my newly shifted rented accomodation.they have taken the installation charges and told that gas refilling needs to be done.for this i have paid for refilling and installation charges of Rs 4000. But after installation on the following day,the ac was not working and samsung when contacted told that ac was wrongngly installed. After two days they told that while refilling of gas the gas chamber of outdoor unit is damaged and they are asking for Rs 6000.Now it is not my fault it is the fault of samsung.Why will i pay for damages done by their franchaisee while installing?Please resolve my problem since they are not listening to me. i have all the documents in support of my claim such as installation receipt,disinstallation receipt etc.compliant no with samsung is 8456132650
