I am so sick and tired of Cellc C overcharging their customers !!!!

<p style="color: #555555;">have been havinf ongoing disputes with cellc. My tariff that has been changed without my consent and then being referred to a Cell C store ., because customer service has nothing to with it ,? really ? is that how you represent yourself ? </p> <p style="color: #555555;">I have been charged for a sunscribtion called BASEBONE and i do not know what this is .. i have never even heard of this and they have been charging me over R100 .. since then ...R130 - R150 and then Cell C advisors tell me that it has nothing to do with them .. I have a wifi ****le ... which makes use of data ..so how in the world do they get my number .. surely they should be notifying their customers and stop this fron happening.. being charged such excessive amounts ? surely they should be able to stop this ? they are refusing to refund me for all the mess that they have made to my account ... including this subscribtion that i am being charged for and i have really had enough now</p>
