A reply received but no way of dealing directly with Rain complaints

I received an response from Mosa at Rain to my initial review, requesting for me to obtain an ticket number in order to assist . There is no way of dealing with Mosa directly, and have to write another review in order for Mosa to reply. I have been back and forth with the Support team who have attempted to assist and they can only pick up: MSISDN: *** surely there is a log history. Please have the common courtesy to give your details to correspond further (Not on Hello Peter)and get this resolved!
