Contract Cancellation

I had an ADT alarm system in the house. So, I lost my job so I decided to cancel the contract because I couldn't keep up with the payment. So, I called the ADT and spoke to Simanga. He phoned me days later and said to me" I spoke to my manager about your situation, and he said we can give 3 months free service, maybe you can find something and continue with the service". I agreed to that.

Two months down the line I received an invoice of R1500, and I was surprised. I called Simanga and asked him why am I receiving an invoice because he said the service is free for 3 months? His response was " When you accepted that 3 months free service you forfeited the contract cancellation" I said to him, but you didn't explain that to me when you give me that free service, you were supposed to be upfront to me about that so that I can make an informed decision. He said sorry my friend, you have to pay.

I find this hard to believe and highly *********. I sent an email to his manager, and he apologized and promised this will be sorted. Now I'm getting calls from their call center telling me to pay. I requested call recordings from them to prove that Simanga misled me but they're also refusing to give them to me.

Can you please help. I want this debt to be cancelled.
