Confusion towards service provided

The only thing that I went to do was change my mobile number inside the branch of postmasburg. At first the system did not want to registe my new cellphone number and halfway through the process there was an system error on her workstation. From there the cellphone number could not be added to capitec's system although the change was successful. Left the branch and as soon as I tried to swipe my card the teller at pick and pay asked me why am I using a lost card. Now nowhere did I stop my card myself. Went into the branch of postmasburg again and then was assisted by another person. At first she confirmed my card was indeed stopped. Further more she enquired where and when the card was stopped. It was confirmed that the card was stopped by the first teller that have assisted me. The lady insisted that she have not stopped the card she only changed the number. But obviously sh is leaving out the fact that there was an system error during the process of changeing my number. I asked whether it would be possible to activate the same card again I mean there was absolutely nothing wrong with my card. I refused then to pay the R70 fee for a new card as the old one was working and got stopped through no fault of my own , and I needed a new card. The second person that assisted me replaced my card and then transferred the fee from her own personal bank account to my bank account. Essentially paying for the banking error that have occurred herself. Now the service from the second teller that have assisted me was impeccable. She kept her nerve and she absolutely did her job in assisting me. Now I feel why should she be responsible and even pay for te card out of her own pocket. The service I recieved from the bank was atrocious The service I recieved from this indevidual was really the best I could ask for. I would kindly provide time date ad the persons involved in a private message if capitec dare to reply to this.
