Shocking service from Bestmed

Poor customer service . I have been sending the stupid docs non stop. The last one was sent on the 14th. They then decided to keep quiet until yesterday when I asked them why my account was not debited. They then sent me an email asking me to send the same docs I sent in the 14th October. I give up. I am treated unfairly by Bestmed maybe I need to look somewhere else. If I struggle before joining them, what will happen after I joined them. Shocking indeed!!!!!
