Have to Pay R300 for Warranty repair on a Brand new phone that's 3 Months old.

I'm extremely disappointed with Cell C. I Signed up for a brand new contract for a P30 Lite on the 11/09/2019. 3 Months later on, my phone wouldn't charge because the battery is faulty and it also did a boot-loop. I Booked my brand new phone in on the 12 of December 2019. a Whole month I've been trying to find out what is the progress on my Cellphone. Now they tell me I have to pay R300 for an insurance claim on a brand new phone battery that has a factory fault. This is ridiculous. Don't take out a contract with Cell C they rip you off. I wouldn't even give them a Star. Only good thing out of this whole experience is the lady at Cell C Danika that has helped me all the way. To you I say thank you.
