Bad and disgusting service

My late husband had two accounts with Cell C. I submitted all documents requested from me Aug 2017. The contract for one account had ended and requested them not to renew. I was advised to continue with other account and given banking details for payment purposes. On 02.03.2018, I was surprised that my line was disconnected. Went to Cell C shop and I was told the account was in arrears and wont open the line till its settled. I settled both accounts on 07.03.2018 and send the proof of payment to their legal department. To date( 09.03.2018) my phone is still blocked. I am missing on so many important calls and opportunities. What is disgusting is that when you call the legal department, one one answers the phone. You will stay on the line for an hour with no answer and your airtime gets exhausted. I received a call from Maropeng at Cell C complaints department on 10.03.2018, requested me to buy a new sim card and will open my line on 12.03.2018. No one called me yesterday and even today and my line still blocked. I have paid the account, what more do you need from me? Can I have my line back as in today
