Bad customer services

Good Day I am honestly appalled by the contact centre agents of this company, My Wife has a credit card and it is in Arreas and they sent someone to my wife's work imagine and the person that visited my Wife at work advise that she can make a payment arrangement of R350 a month, this arrangement was made and has been paid successfully every month, now Africn bank is spamming my Wife with calls and when she answers the call the agents are bullying her in to making an immediate payment and arguing with her to say making an arrangement does not help she needs to make a payment now today and then ask my wife why does she not have money if she is working she must make payment. this is really terribly service please address your staff this is not how you talk to people if you do not know how to be professional do not come with your bad attitude and call clients.
