No account but order was placed Online- Miracle?

I placed an order on the 8th August 21 as Takealot is my only Online Shopping I do. Payment went thru same day 13th August 21 at 10h08, I called to check why I did not get an sms nor an email confirming my delivery but was told they cannot pick up any account under email addresses I gave. 1st one was a work email which was changed to personal due to being retrenched in June 2020. Consultant did mention that I email her proof of payment which went thru, I did so. At 15h35 on the 13th August 21, received an email stating that Takealot Financial Dept stated that there is no account under any of the email addresses I gave. I emailed back late yesterday to ask why no one called also needed clarity... All the years I purchased from Takealot, I have never received such a ridiculous reply as my understanding is - no account then no payment will be generated? Is this not true? 14th August 21 at 06h52, I receive an sms advising me that the delivery will be done today before 5pm? Confused? Why would a delivery then be scheduled when no one at Takealot could find my Account or anything linked to my email addresses? Asked the consultant to also ensure my gmail was being used but no response to that. Where did I go wrong in this? I am totally confused - who did not do a thorough check, me or Takealot? Please can a Supervisor or Manager call me? Cell ***
