Disregard of client integrity

I ordered hardware from the supplier and performed an EFT on Thursday morning 11/6/2015 at around 07h45. I needed the delivery that same day, as I had a shipment of concrete arriving the following morning. The payment integrity was rejected by Magnum, despite sending them the proof of transfer as per my bank (Absa). They insisted that delivery would only be performed when payment was reflected on their account. The fact that I was transferring from Absa (my bank) to Standard Bank (theirs) was of no relevance. Understand that I could not delay the concrete delivery, and this was communicated to Magnum. Despite my repeated telephonic communication with them, they refused to deliver, forcing me to cut away from work to perform a credit card transaction at their premises, in effect paying for the same product twice. Both transactions have gone thru my bank accounts and to date, despite their promises to refund one of them by Saturday 13/6, I am yet to see that refund.<br> Sum total of the experience, I will NEVER again deal with that company, and will at every opportunity inform whomever is prepared to listen, that that is one company should NEVER be engaged with.
