Double paid membership

I am struggling to receive a response or assistance from your customer service email about this issue. I updated my banking details with them shortly before my debit went off and paid via eft. the debit did also go off my previous account and I emailed them documentation to advise them of this and find out a way forward but nobody has gotten back to me for 2 days. I just want to find if a refund is in order for my eft payment? A prompt response would be appreciated
