Trai — unwanted channels in bst

Address:

263139

I am getting a lot o[censored]nwanted channels in my bst north and want to remove a lot of them as it is costing me unnecessary slab fee on adding required paid channels.
As per the policy 100 fta channels should be in bst but i am getting more than that.
I am not willing to watch the channels as these are just a wastage of money...
Hoping for the best resolution from your side.
