Haier India Deep Freezer — Sr no HI[protected] - ac same problem repeatedly

Same complaint repeatedly for several months. As my ac is on amc, service center guys aren't willing to attend and resolve. Within 6 months, many complaints are registered in my ac. As they are money minded, they are demanding money for service even in amc. Already raised mail from 5th may to till now to higher authority, still no response. If the same persist, legal proceeding is the only way to complete this issue.
