Received a broken phone and Telkom refuses to replace it

<p>I went through the lengthly process of upgrading my contract at the Telkom store only to receive a phone with a damaged LCD. </p> <p> </p> <p>I took it back within the 7 day period and Telkom told me they could not help me as their technician was not in, I should come back the next weekend. </p> <p>I went back to the store at least four times more in order to get them to assist. </p> <p>They refused point blank and said that because I didnt open the phone in the store I waivered my rights to bring the phone back in 7 days. </p> <p> </p> <p>I am now paying R320 a month for a phone that I cant use because the screen is completely purple. </p> <p> </p>
