Edgars is getting worse by the second.....

I have an account with them. Always pay on time with EFT. End of Oct 2020 I made a EFT payment to them. Then 2 weeks later Nimble Collections phones me and asked if I paid, because they can't find the payment. Also asked me to send bank statements to proof it. Which I will not do, of all these ******* going around. I went to the Edgars store to find out what is going on, they brought it to my attention that the banking details changed and that they are also under new management. Now I am penelised for late payment and the decreased my limit.
