Double deduction

<p>I pay monthly per debit order on the end of the month. Deduction was made on 31 May. Now today I get an SMS - Thank you for your payment. MTN again deduct a premium. I went to them and they confirmed that the payment of 31 May was received. I asked what about the deduction of today - when will they refund me. O no I will have to wait till the payment reflect, then i must provide them with a bank statement reflecting the deduction that was made today. I asked how long does it take to refund me, the lady responded to say that their turnaround time is 21 working days. in other words after the end of June I will be refunded. Most wonderfull thing is that my husband contacted me now to say that he to received a sms from MTN, thanking him for his payment. His account was also paid on 31 May. What I don't understand is when you take out your contra t you indicated when the deduntion must me (Stop order date) so if you indicated the end of the month adn it ws deducted and they did receive the payment, WHY deduct again on 9 June again. I am out of pocket!! </p> <p> </p>
