Unauthorised debit on my account, still no refund!

I cancelled my contract with Chubb and the last debit order was 1/4/2015. On the 1/8/2015 (4 months later) Chubb debited my account with R320.00. I contacted Val Pillay and was informed that it was the collection of the radio. I personally returned the radio and luckily insisted in proof. I emailed the proof to Val on the 2/8/2015 and after numerous follow up emails she confirmed that I would be reimbursed in 3-4 weeks. At the beginning of September I followed it up again and she sent me an email confirming that I would be reimbursed no later than the 14th. Today is the 16th and I still haven't been reimbursed. When I contacted Val AGAIN she emailed stating that she would follow up with head office and revert. I'm still waiting. She is impossible to get hold of and frankly does nothing about the situation when you do get hold of her. I am going to share my negative experience with all my neighbours in Ballito via social media as my dealing with Chubb have been nothing but shocking!
