Edgars account

I'm really not satisfied with the service of Edgars. I was a client with Edgars for more than 30 years. In November 2020 I cancelled my account, everything was paid up to date. Since today I haven't received confirmation of cancellation or closure via email or SMS. If I call Edgars I'm transferred from this person to that person and then I'm told the person that can assist me is not available and they will call me back. I still haven't received the call
