Vitality not allocating debit orders

<p>I have been having trouble with Vitality from last year. They kept on inactivating my account. When I ask them about it they say they are unable to locate my debit orders. I sent them proof of payment then only they activated it. This year again they inactivated my account. Again they asked me to send proof of payment of which I did again. I asked them why is this happening they said that they have not been allocating my funds. While I was busy with this query I noticed that recently they have not being debiting me. I called and asked them why cause I arranged for my debit orders to go out in the 20th of every month. I arranged for with them to pay the outstanding debit orders but they told me that my account will not get activated until I pay those debit. My question is who is at fault here. Firstly Vitality was not allocating my funds. They stopped debiting me 3 months back without my permission. Now that my account is in arrears because of their poor service. I'm struggling to get my account activated.</p>
