Bad customer service

My second complain, apparently my number was deleted after i had the number for 11 years, with no communication, because i use to receive my statement via e-mail now the decide to cancel all my contract without any communication. now my account have been handed over, again without communication or details to call for payment arrangement. so I manage to get the details and I requested a statement and banking details to be sent on Monday till today I have not receive anything. how to you expect me to pay if I do not know what happening, no communication whatsoever.
