Bad customer service

Hi i sent R1000 to a capitec bank client TV Mahlangu bank account *** by mistake. I checked at my app to revise stop or freeze the transaction. I googled the toll free number ***i spoke to nonhla who tried to call tv mahlangu i was cut off. Due to the fact that i run out of airtime. I was shocked i thought it was a toll free number. I then bought airtime recalled spoke to shaun who had a bad line shaun blantly didnt want to assist me. I asked nicely since he was not willing to assist me can he transfer me nonhla or someone who can assist me but he just refused and he didnt care. Cause nonhla was trying to assist me by call the receipt . I just need capitec bank to revise or stop or freeze my tranfer. Also the capitec bank app needs a least one freeze revise or stop option. The toll free number ***should be removed cause its a scheme to suck clients airtime. I lost about R80 of my airtime due to the scheme. The consultance must be able to call back clients who are duped into believing that it is a toll free call or some like me who run out of airtime. Bad service at all fronts
