Complaint

I bought two cell phones on December 14/12/2023 but one had a speaker problem in the same month I bought the phone, but I couldn't bring back to the store on that month because my son was on holidays so when he came back in January 2024 I took it to Ackermans Brooklyn branch to be repaired on the 12/01/2024 so I was advised it will take 21 days so after 21 days I went back to check I was showed by sales person that they have been doing follow ups but they did not receive service from repair centre,I even sent an email to Ackermans customer complaints on 17 February 2024 they promised to come back to me I am still waiting for an email from them,now I received a call yesterday on Sunday 25 February from Ackermans from a lady called masidiba who told me that her manager saw that matter takes too long they are deciding to replace me with a new phone I must just come with a slip,I went to the store today the 26 February 2024 when I get there I told them my child want the same phone again but the lady by the name of Masidiba told me now the price of the same phone they told me they are replacing is now R1099 I should pay the difference but I told Masidiba on the wap site it was still showing R999 I asked for the manager cause how can I pay a different if they are to replace with the same phone that can't be repaired so the manager by the name of Nthaby also told me that the exception was done by someone at the store in which was not present was at the meeting so they can't override the price I must come back tomorrow,how can a manager of a big store like that tell me that, so I told them they must refund me cash they refused they said the will give me a gift card so I can go but at the other Ackermans branch if they can't override the price in their store what makes them think the other branch will, can I please get help please 🙏
