Pick n Pay - charge for a an online order not received - 4 months later still no refund

I ordered groceries online at the onset of the Lockdown for collection, initially on 26 March 2020, when I arrived my order was not ready. I went back a few days later but the assistant in the shop was still running around to fill my trolley. I waited in store for more that 45 minutes, after which I decided to pay for whatever items I was happy with, the bulk of which I left. The assistant advised that she sent an e-mail to head-office to have the order cancelled and I should not worry. When I checked my bank statement 3 weeks later, the amount for the online shopping was debited over and above the debit for the few items I decided to buy. I have e-mailed the PnP customer service e-mail address and copied the store (Brentwood Park) on 24 and 28 April, requesting my refund. To-date I have not heard any feedback. I would really appreciate my refund, without having to go in-store again, the reference number is 369302. I posted this on the Pick n Pay Facebook wall and got a response to say I will be assisted (13 May 2020), to-date I am still waiting.
