Systems don't work and I'm fed up

• On 5 June, I received a call to upgrade my tracking system. I indicated that it sounded interesting, but I had an issue with my panic button already and would like for it to be replaced in order to continue with the new contract, • On 11 June, I received a call from a lady and she said the panic button would not be replaced even though I told her I had done all the trouble shooting more than once with her colleagues. • After my call I sent an email to cancel the contract as the agreement was not being adhered to and I was within the cooling off period. • On 12 June I received a response that I would have to pay R3400 to cancel the contract. I responded to the email asking why I would need to do that as I was within the cooling off period AND no additional hardware had been installed. I additionally called their customer care at 13:28 on +***0. I was told after the lady had confirmed with her supervisor that it would be cancelled with no penalty. • On 1 July, I received an invoice for pro-rated June service and July service. I forwarded this to the debtors’ department notifying them that the contract was cancelled on 12 June and thus I did not owe anything. • On 4 July, I received a call telling me that my account was in arrears. I notified the lady that my contract had been cancelled so I did not owe anything for July. She notified me that the contract had not been cancelled and I was in arrears. We went back and forth for a while, and I eventually hung up and emailed the customer care department. On 7 July I again received a call that my account is in arrears. I am fed up because I have done everything right and it seems their systems don't work
