Optimum review: cablevision not honoring contract

04/24/11 i called to cablevision and had Mr.Brian giving me a deal:for 2 years i have all 3 services after all taxes for $135.72.I called to confirm appointment 04/29/11 and Mrs. Cristina added HBO for $4.95 per month so my bill would be $140.72 I was waiting tech next day but he came with wrong box.He still connected and left taken alone old 4 boxes, router and old bill[while he was in the house i got letter from cablevision stating deal was off due to lack of my old dish company bill.I called cable right away and Mrs Patricia requested tech to take alone old bill(i gave him phone) and told both of us disregard letter.Next day i was supposed to get right box for HD TV but tech never came, despite i was called 8 times by cable clerks to make sure i am home and waiting.Finally when i called cable at night and complained i was promised 1 month free for my trouble and given next appointment for 05/04/11.Tech #2 came with wrong box again.He spent 2 hrs in my house and called for instructions but still left without doing what he was supposed to.Next tech came 05/07/11 with right box but no idea how to hook it up.He spent 3 hrs in my house, left, came back called to office but finally got it up.By 05/16/11 i received letter we owe to cable$100 for unreturned router.I called and Mr.Douglas said tech #1 misplaced paperwork with confirmation of old bill, 4 boxes and router given by me to him but, after having me on hold almost 20 mins. he came back and said it was found after he contacted tech #1 boss and i should disregard letter.June was uneventful but by 07/14/11 new bill came instead of $140.72 i have written by cablevision contract for in my hands for $220.56.I called and got Mrs.Tiffany said i, ll get right bill for $140.72 but instead she called me back next day and said i need to provide pld dish company bill or my deal with cable would be canceled.After i told her it was only bill i had and old service wasn, t on my name and i was 3 times through it with cablevision and 3 times was confirmed they have it and my deal is on she said i should find way to get it again.PLEASE HELP ME.I am disable person barely getting by on disability payments.$80 per month will strip me of food or medicine expenses beside i have a written contract with cablevision, confirmed 3 times and shouldn, t be responsible for cablevision, mistakes.My account #[protected].Yefim Rabinovich
