Authorization failed but went through and no speedy results from Tymebank

Made a payment for petrol at a speedpoint by BP gerage . It went through on the sms they sent me, but was declined as per the slip from speedpoint. This was my first payment using the card. I called the call center within the hour because the transaction was not reversed.. they say they cant help me because its weekend and the people working with it does not work on weekends. And that they can only help me on Monday but even than it can take long. Now I cant pay for the petrol and had to make an inconvenient loan from a family member. This is a humiliation and I consider it as theft as there should have been messures taken before hand . No other bank allows this and Ive never had this inconvenience with any other bank
