Vodacom Online disappointment yet again

I would not recommend Vodacom Online to anyone. his is now my second experience with Vodacom and it is disappointing. I placed an online order on the 15 May 2023 and used a voucher of R5000 to pay and paid a difference in using my card. The order was successful and I received an email confirmation with my order number. On the 16 May 2023 I received an SMS informing me my order has been cancelled and if this is an error i should contact 081945 which I did immediately. I was then sent from pillar to post and told I cannot be helped as this is not the correct department after being put through to numerous different numbers. I was then given two email addresses to email my issue to, *** and *** which i emailed on the 16 May 2023 and followed up on the 18 May 2023. I have still not received any response. I need my order re-instated or my refund and a new voucher.
