Edgars Account is hell

I paid up my account in 2017 and made several calls for the account to be closed, few months ago I just started receiving monthly statements and texts, seems as my account is open again and they telling me I will be charged service fees and when I call I wait for more than 2 hours to be helped and when I reach EDCON they say they have no records of my account I just call RCS and when I finally reach RCS they tell me my account was opened with EDCON I must deal with them,

The service is pathetic and I’m tired of wasting my time and airtime calling callcentres that are not helping at all
