I disputed XXXX, XXXX, XXXX, and XXXX totaling {$6000.00} to citibank cashback mastercard against a merchant that debited my account last XXXX 2015. My mom asked the the merchant to credit my account {$6000.00} through email, for the service was under her name. It was approved by the merchant, and we forward the email to mastercard dispute dept. During that time, citibank mastercard conditionally credited {$3000.00} towards my mastercard. Should it have been a total of {$6000.00}? After several weeks, only {$3000.00} was credited to my mastercard. I called mastercard and asked about the other {$3000.00}. Since then mastercard has not given me a clear answer why my account was not credited. XXXX dispute customer agent said that there could have been a mis-coding. What is this mis-coding? I asked several supervisors later and none would tell me. Mis-coding? 
I have been doing all the calling to resolve this problem. I have talked to many supervisors. All have promised to investigate and call me back and not XXXX of them ever returned my call. I have been ignored constantly. I think that citibank mastercard is avoiding my request. Please help me resolve this problem. From the beginning, I have followed all mastercard 's steps and now something is wrong. Mastercard is not being transparent nor have the many dispute supervisors, who promised to call me back, returned my call, emailed me, nor sent a mail. 
My mother emailed the merchant requesting why the company is has not sent {$3000.00} to my credit card. The merchant has not responded yet. It is their policy to credit my Mastercard account only. It does not send money in no other way. Please help me.
