Disgusted in the service you provide

Good day African Bank,

I had called your call centre to lodge a complaint regarding my name being placed on default. i called on the 14/02/2019 and advised the consultant that i have signed an agreement for both accounts and have screenshots from the tracer which was sent to my offices and i asked about this before i signed and he advised it was for both. I received an sms advising me that i will be contacted by the 16/02/2019, i received no call or point of contact. I then received another sms advising i will receive feedback by the 18/02/2019 and still no feedback. I was then advised the complaint was closed and resolved. Now i would like to know how that is possible when no one has even spoken to me . i then received a call back yesterday on the 21/02/2019 and the call once again cut and no callback. So now i have a default record from a company who is not willing to sort their matters out. If this is not rectified i will be taking this further.
