No contract - why debit my account?

Hello accounts department<br> <br> I made an upfront payment for my gym membership for one year at lakefield benoni and from there on I started getting debited. Why did this take place without contract?<br> <br> I have not gone to gym for one and a half years now and still you have carried on debiting my account even when I put stop orders. You have carried on without a contract for debit order. I herewith request an immediate cancellation and refund.<br> <br> If you are unable to supply me with a contract copy that says otherwise, you can expect a summons from my attorney.<br> <br> Let me know if you need more details.<br> <br> Best regards<br> Rainer Xavier Botha<br> <br> <br>
