SST is the company that bought all of Wells Fargo's personal loans a couple of years ago.
I used to make payments, but if you were even a day late making that payment the phone calls started.
I ended up getting about 10-15 calls a day - which I stopped answering. I now don't have the means to pay them my regular monthly payments and I've talked to them to try and explain the situation and even set up an alternate payment arrangement, and yet they still keep calling even thought I met the new agreed payment arrangement. They are harrassing me, by definition and against clearly defined laws in Ontario.
Stay away from them if you can
