Can anyone get thru to Account Billing at Supersonic??????!!!!!!

Last week I received an email from Supersonic to say that my account is in arrears and that my service will be suspended. I have NEVER been in arrears. I tried contacting them last week and it is virtually impossible to get thru on their number. I eventually managed to get hold of someone via their whatsapp support and they said that for some reason my payments were not allocated. I resent my proof of payments and was assured that my the payments were allocated and my account was no longer reflecting in arrears. Today I get another email telling my again that my account is in arrears and that my account will be suspended with immediate effect!! Again I try to call and can’t get thru!! this is ridiculous!! I have rep**** to the email with the proof of payments again!! Why is it so difficult to get thru and speak to someone to understand what is going on???? I have never had an issue until this month. Apparently now there are issues at Supersonic with payments being allocated and now they want to suspend my line???!!!! Super frustrating!!!
