Incorrect size delivered

I am utterly disgusted in the poor service I’ve received from Woolworths. I made an online purchase on the 26th of August and by the time my items were delivered an incorrect size of my T-shirt was packed. You then advised that you’d send someone to collect it and deliver the correct size item but more than 10 days later I have still not received the item I purchased. Secondly your courier guy just pitched at my house with no notification to collect the incorrect item(which you didn’t waste any time on) yet I am still sitting without an item I purchased. To say I am disappointed is an understatement because when that item was purchased it was for a function that I was supposed to attend(hence I purchased it on time) but sadly you messed up everything. Your customer service is useless. They give information that they totally fail to honour. So far the only people who’ve been taking the initiative is your Instagram team but every one else has been over promising and under delivering. I’ve been such a loyal customer of Woolies and have spent thousands over the years but to be treated like this is highly disappointing…
