Dial Direct Value Added service ****

In 2015 I took out a motor warranty policy, one of the so-called "value added" options offered via Dial Direct, but I believe the police is managed by a group called 'The Innovation Group". In 2018 I wanted to put a claim in when my power steering failed while on holiday in Kgalagadi - long story short there were very many excuses and they refused to pay the claim. I then cancelled the policy and they confirmed in writing that it will be canceled in 30 days. I never gave it any thought again, but this week I was looking at my bank statement and I wondered why there was 2 DialDirect debit orders on it - the one I recognised as being my house content insurance but the other for R257 was strange. I enquired and it now comes to light that The Innovation Group never cancelled my debit order and it has been coming of my account for 4 years - even though they told me the policy was cancelled in 2018 - that is over R13K off my account over 4 years!! Now they simply do not respond to my e-mails, I called and the guy said he will cancel the debit order but that is not the point, I need a refund for the 4 years they *******ly deducted money from my account - I do not know what to do other than laying a ******** charge - Dial Direct says it is not their problem, I find that hard to believe as well as the debit order on my bank account clearly state it is for Dial Direct
