Waiting for Feedback - Migration???

I have sent an email last week with regards to migration and I never received any response. [Reference number S3-GMB3L-LQH2R]. In the beginning of the month l was by Canal Walk and they couldn't assist me because they were offline. Then I emailed customer service and now I get no response. I am not happy with the contract thay I currently have. All I want to know if I can change my contract similar to a Top Up. I have upgraded in December 2015 and I was told I can only do a migration after 3 months which is in April. Is there anyone who can assist me with my query?
