Received same scam message re Amazon purchase

Scam text
It came one after another about massive purchases and asked to return call to (08) 6245 2502

Before getting these text there were robocalls - designed to see if mobile number is active or not

I just got exactly the same message. I called the number they linked and two separate ppl (Indian accents who said they were with Amazon) told me someone from Ireland had hacked my IP address and made the purchase on my Amazon account. They knew my name and address and mobile number and told me I needed to tell them my full card number (they had the last 4 digits) and bank I used so they could contact the bank to stop the transaction. I refused as it felt wrong but they had obviously gotten into my Amazon account somehow as they knew my previous purchases. f*cking creepy. Looked up the number and came across all this similar info. Also called the mobile number that sent me the initial message - it was just a message service. Contacted my bank and they advised I change password on Amazon - I removed my CC from there and may just delete account.

Called this number after receiving a text advising my card has been charged for $4798 for an Apple Mac book Pro. Reported and blocked as a scam call.

I just got one via text msg from unknown mobile number... same thing. Alleging confirmation of purchase from Amazon if I do not call this number. SCAM.

Caller: Unknown

Strange that O/No and date are the same!! And use of 0 for O throughout.

I received a message saying: "your card charged of $4798.99 for Apple MacBook Pro 15.4 order id F08021MR at AMAZON on 08-08-2021. If You DO NOT, Call (08) 6245 2502"

SCAM

Scam message to call this number (08) 6245 2502 as my Credit card has been charged thousands of dollars on Amazon shopping.

Text... Your card has been charged $5,200 for a microwave purchased from Amazon, call this number if you do not (bad English) Did not call the number.

Received text saying my card charged $5255.34 on Amazon for microwave

Scam text from 0478 599 355 - "Your card charged $5255.34 ..." Order ID spelled with a 0 from "AMAZ0N" and then to call the number (08) 6245 2502 if I did not place the order.

Don't think so. Total scam!

Caller: 0478 599 355

Spam text message in broken English saying:- Your card charged of $4890.00 for PANASONIC Mirrorless camera. Order id P080321LX at AMAZON on 08-04-2021. If You DO NOT, Please Contact (08) 6245 2502

Received a text message saying I'd been charged $4,890.00 for a purchase from Amazon. Nothing showing as pending on my bank account. Text message said 'If You DO NOT, Please Contact (08) 6245 2502'. I called the number from a landline and it was answered by 'Gary from Amazon'. Gary had an Indian accent. Googled the number and translated jpnumber.com website where it basically advises it is a telemarketing/call centre scam number.
