Terrible customer service

As EE customer, I was offered broadband deal which i took. it got to moving home. I rang them to change my address and request a move service. 1. I was given a date all services will be moved etc , the following day i received a call from another representative checking details- I could not believe my ears. told that a new contract has been set up for me without my consent so i refused also it turned out that they could not provide me with the same service i had originally signed for. and also asked them to confirm when was phone contract finished i was then informed that it finished in April. No warning nothing but they are happy to collect money. i ring up today to take up sim only and they try to sell me what i dont need they kept me for 30min on the phone. still i refused what they were proposing. so, decided to cancel my contract, while confirming my address - I found out that it has not been updated to my new address as the company run 2 different system ( every company does) I asked to speak to the complaint team and told that they dont have a complaint department only can speak to the manager who will take the complaint on board. unbelievable. I never experienced the level of incompetency and very bushy to get you to pay what you dont want. A big company withoutcompalint team definately NO go. please people be aware
