Is there link between Spur and SA Bank *****STERS

tried ordering via your sms special I received or full chicken schnitzel or steak for R139. Tried ordering this only to have problems at payment stage. Waited & waited gave up. Then I got sms of price now being R129. Yet always when I got to the app it's like R166! Tried again... Again problems in redeeming R50 voucher I normally get. After that I get ****mers calling from Standard bank ***** dept. A bit too serendipitous for these ****mers. Any links? Standard Bank, Absa Bank, Capitec bank, Nedbank and FNB
