Jaquar — wall mixer has become rust with black dots

Address:

2/921G Nethaji 6th Streer S R Nagar(North) Mangalam Road Tiruppur, 641687

Actually i made a complaint first about the wall mixer has rust they gave a liquid and they charged around 250 for the liquid then why should you say its free service for 8 years and even after using the liquid again it has rust with black dots again i made a complaint the service guy came and he asked 500 rs for sending the tap for lab test and we refused to pay that instead we asked for the address and we told we will send it he refused to give that address and he gave area manager number and finally they didnt send for the test and they told if it went to test also we cant do anything it will be returnes as same then is this the way how they treat customer i have purchased many taps in jaquar only the wall mixer has this problem but the service is not proper why shoul i pay more and get irritated by the service guys its free service for 8 years then why should i pay for the service there is none other than shifting the brand
