One of the worst services when you want to cancel. First of all they expect you to run around to return the equipment. Their cancellation mail says that it is the customer responsibility to return the equipment within 7 days which is absurd.
Other problems you will face
Disinterested and rude behaviour of staff
Contact numbers given seldom answer the calls
Pathetic customer service
Since you are cancelling the service, they will try to squeeze every possible penny from you citing various reasons - Don’t fall for their tricks.
If you still wish to buy their services, god save you!
