WOOLWORTHS CUSTOMER SERVICE.......WHAT SERVICE?

On the 5th February I received an sms, showing that a large amount of money was paid into my credit card. When I queried this amount with Woolworths Financial Services they told me all they can see is that it was a payment into my account and couldn't tell me anything further. I then managed to see on my online app that the reference on the payment stated "balance write off". I then tried again to get in touch with Woolworths credit card division who also couldn't tell me what was going on. My card was then blocked and when checking my credit report they have now closed my account. I have sent numerous emails and tried numerous times to phone but everytime I get a different person who again can't assist me. I have even resorted to complaining on the Woolworths Twitter page and Facebook page but again I just get referred to their Woolworths Financial Services team who just never come back to me to explain what is going on. I am an excellent payer. My credit reports on all bureaus are good and yet they have gone and done this. Without my consent and without my knowledge. Surely you should call and discuss this with you customer before going into their account and closing it. Where is my explanation? Not an email but an actual call to me to explain what is going on! It is now the 17th February 2021 and I still have no answers as to what is going on. I am disgusted!!!! I have supported the Woolworths brand for years, all my grocery shopping is done there, clothing etc and now this. I'm not sure my faith will ever be restored in this retailer. What happened to customer service? I certainly have not received that from Woolworths at all!
