Incompetence of call Centre agents then when I ask to speak to a supervisor I am told they only talk to someone if the matter is serious so my tablet not being blocked with all my personal info and banking details is not serious???????????????

So Saturday morning some ****s came into my house while I was busy in the back yard and stole my tv ..... but it was only that evening that I noticed my tablet and laptop was also gone when I wanted to use it and I immediately got on the phone to stop the card and blacklist the device..... or so I thought... The lady Lindiwe told me she is sending through a msg to her supervisor who will send me an itc number which must b used to go to the police station. TODAY 10/10/2017 My husband calls me on messenger and the **** answers ??????!!!!! So I freak out they r still using my device and have access to my photos banking details emails Facebook peronal documents copies of I'd passports etc. The call Centre agent Thabang informs me it has not been deactivated and he is going to do it right and send the supervisor the info and they will send it number on at number when I ask to speak to the supervisor about the previous agents incompetence he tells me they only speak to us the public in serious matters ???? needless to say I ask if he does not consider my problem serious of which I have to hang on ..... he comes back and I will get a call from Granny Malinga and an itc number in 4 hours this after it was not done since Saturday .... they cannot see why it is urgent / serious to me having a stranger accessing my personal info..... can someone at telkom please help me
