Bad customer care

I missed a payment on the 25 and called the call centre for assistance which I was on a call for 20 minutes only to be sent a link that does not work and I decided to call again to use a different mode of payment so they gave me an EasyPay number and I made a payment to my surprise the data is not reconnected and it’s now 2days since this happened and now when I get in touch with them I am told I made a payment to an incorrect account and now I need to make another payment, they can’t reverse the funds to a correct number after I provided them with every thing to prove that the payment was made and they can’t find it on the call where I got the EasyPay number, like I imagined the number
