Movember Refund

Good day,

I recently made a online donation to the movember foundation. The first donation I made was R50 and there was no problems with the donation. Later the month I made a second donation of R450. The donation was completed and I believed it was successful. I later received a email from a lady working at Movember who said my R450 purchase was not received. I looked on my FNB account and the Movemeber amount was deducted, but movember says the money was not authorised. I emaild FNB and recieved no response from them. I phoned them today and after 15min of waiting on the phone I received no repsonse from their customer care line. I am unhppy with the service I received and want this problem cleared up as soon as possible.
