Unhappy client

I`m utterly disappointed with the service i experienced. I purchased 3 items online worth R873.60 on the 7th of May 2020. The amount went off my Credit Card. On the 14th of May 2020 i received an email saying my order is being processed but one the items is out of stock and i was going to be refunded for that item back. The item was about R279 . To my surprise on the morning of the 15th an amount of R594.30 went off my credit card and when i check my invoice its the amount of the 2 items i`m waiting for. So that means i`m billed twice for the same items. I phoned that morning and spoke to a service consultant and i was promised that the R873.60 which Woolworths owe to me will be credited back within 24hrs. I`m still awaiting the refund. I had to phone the second time and only to be advised my query has not been attended to..

Where is the urgency and good customer care?????

Your response will be much appreciated.
