This survey in my view is not any good.
One cannot combine this all.
Give a few sub options on each.
An example could be.
Rate ISP on the following:
a. Billing portal.
b. Support issues.
c. Quality of network.
d. Value for money.
All will be highly subjective, yes.
With the current poll, an example.
Telkom infrastructure network is excellent.
Value for money is very good.
They are utter useless if you have to interact with sales, billing or support.
