Unhappy

I am most unhappy and dissapointed with the service received from Standard bank. I did an immediate payment from my Standard bank account into my FNB account it shows as immediate and they have deducted the fees but the money has not yet reflected. This was done on Friday it is now Saturday evening. I went into the branch today to explain what happened and explained that I am needing the money and it is now in the clouds somewhere unavailable to me despite it being an immediate transfer. I was told that they don't know why I had to phone the support Centre who did security checks and couldn't help me I was put through two more times just to go through all the checks again. They assured me that they would phone me within the hour it is now 10 hours later and nothing despite me saying it is very urgent and needs to be sorted or the transaction needs to be reversed back into my standard bank account. I would appreciate assistance in this regard as a matter of urgency as the money is needed and cannot be floating around. Pathetic to say the least and I cannot understand how no one is able to at least just have the decency to phone me back
