Urgent

Good day It break's my heart everytime I see money coming out my account for a cellphone I don't own, I've been trying to get my upgrade since it was due last year April and they refused to upgrade since I'm 87 years and not to sure anymore how things work now days and was some how convinced to go on debt relief... That's besides the point I'm trying to get out I've been with cell c for over 15years and have had many upgrades through them and now they refuse to upgrade my phone and still got the cheek to take money out of my account for nearly a year?? Not to mention the R99 they have been taking off for God knows how long I'm sure about 6-9 years for a Internet ****le which to my knowledge have been discontinued I have asked them to stop taking the money off cause I don't own a phone anymore and I've rightly paid up for the one I did. And yet they still take moneys and the proof is in my statement I've only been aware of this recently from the help of my Gran son they praying on the old because we gullible and tend to forget. I need some advice on what else to do. I've been asked to come in stall and it's very difficult Im unable to go myself due to my age and I need to rely on people to help me I've made two attempts and evey time they seem to be offline and they give me numbers to call and nobody can assist me. Thanks
