Bad service

I'm very disappointed with Woolworths credit card department. I have paid money to Woolworths credit card department using Absa cellphone app and selecting absa benefiary account. Now I've been calling the Woolworths credit department so that they can load it up into my account and they said i must send them bank statement which i have sent up until now they did not help me. I've just received email from Lucille Davids saying that that is not enough proof of payment. I'm so disappointed that when you owe them they will call you non stop now that I want them to load that amount they treat me so bad they don't even worry that you are using money to call them and listen to their music.
