Tata Sky DTH - Tata Sky giving false information to customer and simlly tskjng money from customers

Tata sky provided me Binge fire stick which was not working and due to the lockdown it was not collected by the mechanic nor it was installed. They charged me huge money and also amazon prime membership fee was also charged. Now the prime membership is also cancelled. They do notbsuppoet customers but make money even during the lockdown.
They took money for whole year and did not add the bonus * month. This has happened for * years in a row now. They give false information and make money.
