I have attempted to contact 3 multiple times, initially to provide updated payment details, and secondly to take control of a deceased relative's account - I am the executor of the will, and have all the necessary documents. 3's customer service in this matter has been disgusting - insisting that they need to speak to the account holder to change payment details, even after being told why this was not possible. Then telling me that the process to change the account holder information would take "two days maximum" when they wanted to post a form to me - that alone will likely take more than two days. Further, I cant complain about 3 until I am a customer - so I have to suffer their inconsiderate customer service representatives and inefficient processes just so that I can complain about the same things.
