I expect they swamped with calls along the lines of I cant afford this and wont be paying this.Its easy to be jaded by customers calling, specially nowdays. Agent's shouldn't be taking it out on customers but it happens....could also be a newbie (as they are recruiting like mad at the momen and the agent just didn't know what to say)
I know where I worked they don't tell you how to work out a bill manually anymore in training, your just assumed to know how. Reading a bill is skimmed over quickly and your expected to pick it up on the floor.
I left at the point where the phones where kicking off due the cost of living and the winter approaching. People I still speak with who are still there are not having a good time, just constant complaining easy to see how stressed they are.
I noticed Octopus customer service standards dropped of a cliff since the crisis started.
