Suspended my Number unnecessary

I have been a Cell C Customer for years, i fall behind with my account. They blocked my number before lockdown. I need this number to greate an income and therefore i send emails daily and got no response. I just want to pay my amount due and get my number active. They told me only way for me to get my number active is to settle the total amount of R14 600. I need this number i have lost alot of business because of this. I need this sorted and need assistance from cell c or i am going to lose my job. I will never ever recommend Cell c again to anyone if this is how they treat their clients.
