Shocking service

The service i received left me shocked and underwhelmed. I made an order for delivery with Adega express woodmead, the delivery man arrived on time with my order, he was extremely friendly. i made a payment for my order but their speed point did not print out a receipt. i however received notification that the payment had gone through. later i received a call from the manager Elizabeth, notifying me that there was no payment. i explained how that could not be possible as i had received proof of payment on my side. she continued to advise me that a driver would be sent and that i would need to make another payment. i reluctantly made another payment, in cash this time to avoid any further misunderstanding. This morning (07/08/2019) I was contacted by the manager to advise me that the money was now reflecting on their side and that they can have their delivery person return my money. i was unable to speak at that time and called back. when making the call the manager "Elizabeth" spoke to me as if the error was my fault and explained how i could not have expected them to close off for the day without all the money being paid. i'm not too sure how this was my problem as i had paid and was not the one with the faulty speed point. She further went on to say " i apologized what more do you want me to say" she was only concerned with her organization having their money and not the fact that i as the customer had been extremely inconvenienced. i had to make countless calls to them and run around during my working time for an error they made and their idea of an apology was a joke
