RCS *****

I received a call from RCS call centre they wanted to convert my credit balance to cash and i said no thanks. Few minutes later got another call from 087 number and the lady said she wanted to update my details she is calling from Makro. She said all my personal information. Then she said i must check the sms on myphone. There were 2 sms's. I told her that one has the balance on my account amd the other one had the OTP. She said i must give her the pin and i refused because i know that u can't the call centre agent the OTP and she said my account is in arrears and if i dnt give her i wil pay more. I said it ok i wil go to Makro. I went to Makro they called the caall centre and they said it was ***** and they wil block my account while they investigating they wil get back to me. They never did. The next day i got a call again from RCS callcentre and they wanted to convert my credit to cash and i ask teem which account coz my one is blocked and she said she doesn's see the blocked account and apologized. Barely 2 mins i got a call from 064 number and the guy said he is calling from Makro he wanted to update my details. I just lost it he also had all my personal information. Shouted at him and he ended the call and the sms with the OTP came through. Later that day i received sms that my number is being ported to mtn luckly vodacom declined the request. This left me wonder if RCS is not working with these ********** because they call immediately after the call center. RCS needs to inform all their customers of this ***** because some people dnt know the importance of the OTP and they are left with huge debt of somthing they dont know.
