HORRIBLE SERVICE AND A NIGHTMARE TO DEAL WITH

I have just received an email of a demand letter from Cell saying I have an outstanding amount .After I have posted a complained here on this platform your agent called me and they have cancelled the contract and deducted the amount they said I owed .To my suprice I'm receiving a demand letter and no one has ever contacted me before regarding this amount. I had enough of Cell C and now your ****ing me off again .talk to your team to stop dragging my profile on stupid claims and they must start doing their job professionally. I do not have a contract with Cell C and will not wish for anyone to have one with with them because their service is pathetic .I do not owe you any cent do your job and stop bothering my peace or this will go far .You are depressing me
