I am flabagasted

How is it possible over a series of 11 messages guaranteeing me the price I would be charged that Virgin can still overcharge me ?

We've agreed I'm would pay a certain amount and now my bill has been generated it way higher than agreed

I even asked the customer service person to confirm it in two separate messages of the 11 it took to resolve 

Well I was promised the price in messages so Virgin don't have any dispute available to them 

They also told me my security info was wrong multiple times (it wasn't)

They then called me a weird name (ledge) in one correspondence which I have no idea what they're talking about 

My impression is this person has the wrong account entirely 

Honestly the stress caused by Virgin and their terrible customer service department is not acceptable 

I'm NOT paying this latest bill, I want it changed to what was agreed and I want an person whose fluent in English and not some broken version to resolve this please 

With all due respect there's no point anyone who speaks that broken version contacting me as it won't get anywhere and will just waste my time
