Promises about my refund.

I posted below on FaceBook Tuesday (20/03) and received a response back saying that someone will get back to me... and now, radio silence again, perhaps someone on Hello Peter can give me feedback... I ordered online, for delivery on 01/03 (# ********** 942 ) for between 17:00 and 18:00... when the delivery wasnt there by 18:30 i called... all we pretty much got was "sorry, we will bring it tomorrow"... I had items in that order that i needed for work 6:00 the next morning... so this cost me having to drive to Checkers that time of the evening to purchase the items. Your driver promptly arrived the Friday at around 16:30, so i sent all the items back that i had to buy from Checkers the previous day. All these items were clearly marked so that i can get a refund. Today was now the 3rd phone call to Pick n Pay to find out where my refund is... just to hear that (after being told twice it's been processed) that it hasnt been processed yet.... NOW i wait another 5-7 days.,.. I wish I could tell ABSA to WAIT when it comes to charging me interest. I've been a pretty loyal customer for a number of years (and yes... in the greater scheme of things, I'm a very small fish in a big pond)... this is not the first incident, so now I'm starting to lose my cool, I advised the lady on the phone that my only option is social media - perhaps there are other people with the same issue and we can discuss how to handle this matter.
