My Blacklisted Device Complain and Contract

I’m writing this post to Cell C, as they are not of any assistance. After losing my job, I wasn’t able to pay my contract. My phone got blacklisted, to top it all even my number was taken from me. I am so eager on making arrangements with Cell C, to settle my account. Because I need my phone unblacklisted and have my number back. But no one has been in touch since they blocked my device. Worst part the device is an iPhone 6 Plus Gold. The insurance was also cancelled by them, which I’ve been told it should have settled my outstanding balance. I find Cell C *********** when it comes to customer service. Even if all my misery is sorted out, I don’t think I’ll ever take any contract with them nor refer anyone.
