unacceptable waiting on the phone

Hi I am trying to get ahold of the rcs credit or else the macro credit department for months to change my cellphone number and to find out how much i need to pay them to get removed from transunion, but when i phone , then i wait an hour and get disconncted and need to phone again and again costing me a whole lot of money. i only want to find out if i am paying the right ammount monthly or should i increase the ammount paid because i am paying with debit order and cannot access my online profile due to having a new cellphone number, now all of a sudden i am listed as a bad payer on transunion? i did have a payment agreement with them till my salary gets sorted and yet i am listed? now i cannot get a cellphone contract etc. Please help and have them contact me on ********** 976 or email at **********
