Trai — complaint about fastway dth services

Address:

VPO mallah TEH. Jagraon, Ludhiana, Punjab, 142035

My name is imran from ludhiana punjab. I am regular customer of fastway dth company from three years but now i want to discontinue, so i requested fastway to stop my service from july 1st.
I have paid rent of this month (June) in advance for june 1st to june 30th. But company stopped my services today on 23/6/2019 by saying that if you don't want to continue in july your services will be barred 7 days prior according to trai rules.
So my concern is that i have paid for 30 days but company provided me channels for 23 days only. Is it really according to trai rules???
