Debit order going off after cancellation

At the end of March we gave Bonitas written notice that we planned to leave them at the end of April (as we were tired of their poor service). We received a letter back from them confirming the cancellation effective from end April. In the meantime we joined a new medical scheme. <br> <br> At the beginning of May, our Bonitas premium was still deducted. We contacted the call centre on Monday 4 May to query this. The lady said we were due to exit the scheme only at the end of May, which was incorrect. She asked us to email her the letter we had received from Bonitas and once she had that and could see it said end April, she adjusted that on the system and said she would put in for a refund, which could only happen towards the end of that week. <br> <br> A week later, still no money or word from Bonitas. On 11 May we phone again, the man we spoke to said he can see the refund is pending but will put in a message to speed it up. <br> <br> Today is a week since that conversation and still no money from Bonitas or email/call to explain<br> <br> This is why we left them- absolute inefficiency<br> I am angry & disappointed, & under serious financial strain without my R3149. I doubt they will even respond to this.<br>
