very bad customer service - dont cancel at all

I had apparently taken out this getmore service back in 2012, since then i have upgraded my cellphone with cellc and asked to cancel all added services. I get my statement monthly but dont ever really check it until June 2017 where i see that since 2012 this getmore is deducting my money.. I phone them on the 06/06/2017 and cancel and asked them for proof that I acually asked for this service. They then send me the recording. I then let it go for the past 5 years of them deducting my money and ask for a cancellation. I receive an email on the 07/06/2017 that they sorry to see me go and that this has now been cancelled. the i get my statement in July and see they still deduction. they say that there is a 30days cancellation period. fair enough.. i look on my statement in August, and there they still *****ing my money.. i call and don't get any joy and NO ONE even replies to me or even calls me back.. so i get my statement today 06/09/2017 and what do we have AGAIN, another deduction.. so they once again ***** my money.. I call them and they tell me that its not them, its cell c, I call cell c and they say its not them its Getmore.. oh my word.. i want to just cancel this non sense, its impossible to do that.. i speak to Flossy? at Getmore and she says to me that she will get someone to call me, ask she cannot help me.. then obviously no one calls me back and i have to phone them again.. first they say to me that no one there can help me so i tell them i will hold on until someone comes on the line.. and there we go 5 minutes of holding and the rudest and very unprofessional person called Fisani gets on the line, and spins me some nonsense about me not doing my calculations right and that there is 30 days cancellation, which i ask her, how on earth she works 30days out, and she spins me more nonsense.. i say to her, that 30 days from the 06/06/2017 is definitely not end of July as she basically says they will only refund me for August and September.. which in my eyes is very wrong and not the way that it should be.. i will never refer these people to anyone,, they are no helpful and definitely not professional and dont want to help anyone.. i just received an email saying they will credit my cell c account and thats how they do refunds.. nice..... anyway.. i bet that next month when i look at my statement they will still be taking my money.......
