Failure to comply with contract as sold

During July 2015 I bought two Netstar tracking devices. During the telephonic sales conversation it was confirmed to me and my father that the first debit order would run on 1/9/2015 at which time a double premium for August and September as well as pro-rata payment for July 2015 would be deducted from my account. Devices were installed on 30/7/2015 but no panic buttons as specified during sales conversation was supp****. On 5/8/2015 a debit order was presented to my bank but as I was not informed of this it was declined by FNB (resulting in a financial penalty to me as FNB client) . Today (13/8/2015) I received a SMS that the debit order would be re-submitted on 15/8/2015. Despite numerous calls I was informed that this process can not be changed or rectified. I would appreciate it if the debit order problem could be sorted out and the panic buttons supp**** as agreed. If this issue cannot be resolved I request Netstar to remove the devices and cancel this contract with immediate effect, as I feel that they did not honour the contract as specified.
