No response on account query

I made a payment on the 26th Of December. The payment went through but my account was suspended. I phoned Customer Service but they were unable to assist me, the referred me to your i service helpdesk as i have a specialist account according to you. I cancelled my panelist account 2 years ago as you do not get hold of them when you have account problems, yet now I am back on the panelist system. I have tried phoning the i service help desk but you can only leave a voice message. Till this day they have still not contacted me an my account is still not active.
