Bad service

Home-connect service is very bad. Last month I was told told my payment didn't go throw when they debited I had to do payment via eft.today I did a payment via eft. Later today they debit my account again.I called the call Center and spoke to a lady called Zethu I explained to her that they debited me where else I already have done an eft.she advice me that both payments haven't reflected I understood I than asked her how long will the refund be done.she told me that refunds are only done on Thursdays.how can payment reflect after 24hrs but you guys fail to pay refund I really need my money I can't wait till Thursday
