Reliance Bigtv — no installation done no payment returned, more than an year.

Hi, I have booked a new connection by paying rs.500 to reliance big tv on official website with booking number 14511523 on march 7th, 2018 and got the message about INSTALLATION WITHIN 30 TO 45 DAYS that is max in month of april, 2018. Even after trying to call them after a long claimed days call was not connecting since months and when it got the executive was really unprofessional and said that it will be installed on 19th of June and that i will get a call from them on 18th june, 2018. But again false commitment made and no call or mail received and when i requested them that because they are late and I have moved to another location they said tell this when our technical guy calls. Which is again illogical. Around 19th june, 2018 I called again and they said again give us 5 more days and it will be done and guess what again FALSE COMMITMENT for third time and for change of address they said mail us. NO RESPONSES to even my multiple mails regarding installation or change of address and very very difficult to reach on phone as well. They are doing completely fraud and this been a long long delay and no option even to get refund and I had a blank tv with no connection since months.no entertainment? Highly frustrated and feeling really cheated from a third class brand. I dont know where my advance money has gone and should I get another connection of other company or wait and what about my lack of entertainment due to false commitments since more than year? Please help me fins a way. I Seek all the interest and cost cover for humiliations and false commitments they caused.
