New Customer - Product Complaint

I am disgusted with the level of service I have received from the Telkom branch in the Cresta.<br> I took out 2 cell phone contracts on Saturday, later that night I noticed that there was a small flaw my phone. I went back to the store on Sunday morning and reported the flaw. The sales person went into the back office and discussed the issue with his manager who didn't even bother to come out and see me but instead instructed him to tell me to keep the phone and if it gets worse to come back on Wednesday. I told the sales person that I am not happy to keep something that is not perfect and he assured me that he will call me on Tuesday to come and collect a new handset on Wednesday. So I waited. On Wednesday I went back to the store, the sales associate who assisted me wasn't there and I was passed from one person to another. Then I FINALLY spoke to the supervisor who told me to come back on Thursday because there is nothing he could do as his manager is not there. I was not happy about it and told him he better assure me that something can be done. I returned to the store today to find no managers and no resolution to my problem.<br> <br> Please can someone assist. I am at my wits end!
