Why hand my account without talking to me first, worse after you have recieved your payments

Sanlam handed my credit card account to Norton Attorneys while payments for the credit card were being made directly to them. I get calls from Norton Attorneys and I am thinking they are trying to **** me because I am making payments to Sanlam and Sanlam in return is sending me statements every month on the 15th so I am aware of what I am owing them and its not the amount that Norton is asking me to pay. Yes when I call Sanlam no one wants to explain why my account was transfered to them and why was I not contacted to let me know that the account is going to be handed over, why hand it over after you have recieved payments not once more than once. And mind you the only they handed was my name and number but did not let them know of the payments that have been already payed on the account. I don't want to start with the Norton agents, they are very rude and speak over you when you are trying to explain to them what is going on. Sanlam could not have picked up the wrong group to present them, they are unprofessional in all forms and shapes. I want Sanlam to get my account from Norton, I rather deal with Sanlam then with them. Now I was chating to them via WhatsApp I forwarded them my statement yesterday and were asking for password to open it and I gave them and I am asking them for banking details just because I could not provide the date and amount of payment I person I was chatting too did not give me the account number, I don't know how long I have been asking for it, they will say they will send it via sms and I never recieve anything, this other time the lady from Norton that last one I spoke to said I recieved an email from them with a statement from the and I told her no I did not recieve it and she insistade that I did no matter how I tried to tell her she is not saying okay will resend it or what but is so sure that I had recieved it and telling me that they have sent a statement, like what statement because I have never made any payments to them. Sanlam please please get my account from these people, and why did you send it at the first place we should have talked about it first
