Poor Customer service

I have an account with Woolworths. I consolidated all my accounts with my Bank on 12 July 2018 with my Bank. I have been calling Woolworths daily to locate the funds to my account however their finance department is failing to do that. I have been asked to provide proof which I did. Their call center is so ***********. They don’t care about their customers. On top of that I have been getting collections calls from Woolworths daily, I have been sending e-mails for help. Not sure what to do anymore. This is poor customer service not expected from a Company of their stature.
