UNAUTHORIZED DEBITS ON MY BANK ACCOUNT

I RECIEVED a call from a telesales agent regarding a cellphone contract. During that conversation, some extra services where offered to me such as TechTrace, MagZone, PhoneBox and SafeBase....... i refused these services as i wouldnt be able to afford the premiums... i recieved an sms later stating that my Mobiles Plus order has been declined, yet on monthend i recieved sms's from my bank ststing that i have been debited for those services which i refused. i have the ffl oreder reference numbers: Mobiles Plus (REF: MP-***9-1) MagZone (REF: MP-***9-2) SafeBase (REF: MP-***9-3) TechTrace (REF: MP-***9-4) PhoneBox (REF: MP-***9-5) i am extremely upset as i work on a budget and this has put me right off track. If possible i would like these debits to be reversed. it seems that the telesales agents ignore what you say and try to capitalise on these extra services in order to recieve commission..........
