I decided to switch to another package, called them and discussed the charges for "early contract termination". In an hour received the official receipt with different amount (around £23 above). Called them again, asked why. They agreed that it was their mistake and that they will sort it out. I asked to correct and resend the bill. They refused, saying "we don't send revised bills". I asked to send another confirmation that I will not be charged more than initially agreed. They refused. I asked the operator to connect me to her manager - the manager refused to talk to me, "putting me on list to call back within 48 working hours" (which is at least 6 working days). What do I have at the end? The incorrect bill from VM and no evidence that I will not be charged more. I tried to make a complaint - they refused! I cannot believe that in UK there is still the company with such ugly level of customer service.
