Cell C: Upgrade to a broken phone

Upon an upgrade, i received my new phone.I was excited and happy with it. <br> It worked initially but with the second charge, it did not want to charge. This was exactly 7 days after receiving the phone, on workers day. I tried to contact Cell C and notify them but their operators kept putting me through to other operators and I was finally told that I must contact them on Monday. This meant that the the report was only logged much later than the 7 days and now I must wait an supposed 21 days before (7 days for pick up, 7 days for assessment, 7 days for delivery) or more because I was sent a broken phone and could only report it on a public holiday. I feel it is unacceptable and not my fault in any way, and that the phone should just be replaced immediately. VERY UNHAPPY WITH THE SITUATION.
