MRP Mobile pathetic service !

I took out a contract with Mrs mobile 2 years ago , ever since inception i have not received a statement which is against NCA ruling and when i request for a settlement which I have done 3 times now I have to go via their call centre which has so unprofessional staff . All 3 times the staff refused to email me the settlement letter which is against nca ruling and the consumer protection act. Further when i left an email via the contact. is option on the map mobile website i have not received a response and 14 business day have exceeded. It is against nca ruling and the consumer protection act for an company to refuse to give its customer a settlement letter as well as not forward the customer any statements. Please can i have my settlement letter in writing !
