Double debit orders for 2nd month running

Debit orders went off my account on 24/03 AND 26/03. <br> <br> The same happened last month, and according to my statement from Homechoice it was a KWIKSERVE payment. According to my bank it was a DEBIT ORDER. I had this payment reversed. I have no idea what a Kwikserve payment is, and definitely never made a payment that way.<br> <br> An sms received from Homechoice on 25/03 states that a debit order would go off on 26/03. But one went off on 24/03 as well.<br> <br> On 22/03 I received an sms stating that a repeat debit order has been scheduled for 25/04. I also received an sms on the 22/03 saying that my debit order will only be effective as from May and that I have to pay for March using another method.<br>
