GET IT ACCOUNT INCOPRPORATED IN CELL C BILLING

I was made aware of the fact that I have been paying an amount to an App GET IT on my CELL C statement which I did not use or requested I spoke to a lady by the name of Liven on 01/02/2016 and requested that the billing must stop immediately as I did not request this app she however informed me that I have to give 30 days notice and as it is the 1st of the month it will only be stopped the in March 2016, what upset me the most is that this app`s acc is incoprporated in Cell C billing I refuse to pay for GET IT and there is no notice period for these telephonic accounts GET IT phoned me 9 times from 01/02 upto 05/02/2016 they only let the phone ring for 1-2 sec as to record a call if I did manage to answer the call they immediately cut the call I called CELL C`s customer sevice on 22/02/2016 to inform them that if they do not sort out the problem I will have no choice but to do a reverse payment on their debit order as it seems that they condone this behaviour They assured me that GET IT will contact me before or on 24/02/2016 latest To date nobody has contacted me providing proof that I requested the app. My ref no is *** I am sure there are many customers with this problem
