She cant fulfill her promises

I have open a contract for Huawei P7 phone on the 15-04-2015 wherein i was told that the phone comes with 2 original P7 cover namely black & white, but the black was not available on the day of activation. Nthabiseng promised that i will get the cover the following week on the 21-04-2015, but when i get to the store i was told that the person who is supposed to deliver didn't come so since i was going to Gauteng i was told that it will be delivered to the nearest MTN store which was Eastgate Mall the following week which was around 27-04-2015 but it never happened and the was no feedback, so I decided to keep quite for few weeks which i did. For the past 3 weeks i didn't get any respond on what is causing the delay until i decided to call Nthabiseng on the 22-05-2015 to ask why i haven't got the cover, she told me she was just talking about me so i will get the cover between the 26-27 of May 2015 which never happened until today. So i believe my patience is tested enough for 45 days. If the consultant knew how tough is it to get an original P7 cover i would had received my cover by now as promised but instead i am underrated as a consumer no wonder i am uninformed of the delay.
