If you are an OAP dont use IDM
I tried to join IDM as i used them before but man what a terrible service. I had a problem not covered in the IDM community and used their chat bot. eventually got a nice guy called Ameer but IDM would not let me talk directly to a human on the phone and Ameer couldnt help me. It was a simple problem regarding extra Sim cards but after 5 hours of messing around for a 5 minute problem i gave up. Now im trying to contact them again for a refund and its not possible to explain itr to a damn bot.
