Manually paid and then said to pay again so account one month ahead but account suspended?

I have three tickets that I created with the same issue and have yet to get any response which was yesterday 2020 07 08 (a day passed and no one bothered to get back to me which is a disgusting service) and calling is useless as no one is available to talk to about my issue (I tried the while day and got the same message).

* Can someone get my account sorted out right now as I manually paid the out standing amount on the 29th June 2020 I then get an sms that I must pay more which is not correct as I am fully paid up but I have now paid the extra payment to my account which was not required as I am paid in full. Sort this account of mine out immediately. My account should be ahead now by one month as I have now way over paid which means this month I do not have to pay a cent. Please get back to me ASAP on this matter

Ticket references I have: *** , *** and ***

Can someone reactivate my accounts immediately and get back to me advising me about my account being over paid. Either then credit my account or pay me back! This has caused a lot of issues
