Bad Service *******

I am a customer of standard bank for 8 years now and I must say I'm highly disappointed with the service. I was offered an accidental cover and accepted and then I cancelled it within a few weeks. On 1/12/17 the debit order for the cancelled policy was still deducted. I called them and Michelle assisted me. She said that the debit order did not reflect on their side and I should phone after 15 working days. I called and Michelle was not in that day, so I spoke with a male, he said that the query was added into my name and that it should be reversed soon, this happened mid December. Still nothing, then I called mid January. Spoke to Michelle and she said she would find out from the admin department and phone me at 12:30 that same day, I didn't receive any call from her again. I phoned her the following day and told her that I can't keep phoning after them as it's my time and airtime that I'm wasting and they never follow-up. She said I shouldn't phone them they will call me as soon as they sort out the problem, as she has now handed the problem over to her supervisor. I'm still waiting on the call. This morning on 16/2/18 I receive a call from a standard bank agent trying to sell me the same policy. I then explained to her that I'm still waiting for them to pay back my money and she instantly hung up on me. I'm highly disappointed! After 8 years I feel like changing banks and taking this matter further! Poor customer service!
