CELL C needs to take accountability

So i have done a stop order on my account with CELL C as they couldnt assist or help me as to why i am paying extra on my account. They have suspended my account & the consultant said on the call of 12 March 2021 that i am in arrears & that i will be blacklisted. They quick to blacklist people but cant assist when having a problem or you wanting to cancel a contract or upgrade. I have been a loyal customer for so many years and this is the response and loyalty that i get back. I honestly feel that ITC cannot blacklist me as this is not my fault but the consultants of Cell C. I DONT KNOW WHAT MORE TO DO as i have never been the way that CELL C Is treating me i am disgusted, angry & disappointed that our names can be so quickly tarnished and yet they dont know how it feels because they probably havent been in this kind of situAtion
