R399 - ****LE

Sun 1 Nov I had ADSL Line problems,my son needed to use the Internet for pass Mathematics papers as his currently writing Matric,I bought a ****le R399 + R150 data & never used it as my line went back on.Took it back Mon 02 Nov as it was faulty.The manager assessed it @ store level & felt that I used it & had to be sent away to the Technicians with no book-in receipt it will take 14 days to either get a replacement or not. I am furious that he was not willing to assist or reassure me of giving me the benefit of the doubt.The more I told him it was not used he was adamant that he can see it was. Would replacing the ****le have caused the bankruptcy of Cell C?One of the staff said that they could just do an OBM/IBM & replace it. Instead,he assessed it & the techs will have the same outcome,after all his in charge OF THAT STORE. Who would accept this.You spend R549 and are not able to use the item!!! I sent an email to Cell C customer complaints and todate have not received a phone call from them. I will never buy from Cell C AGAIN!!!
