Unable to get a hold via call or emails

Been trying to get a hold of Matrix since last month. They tried debiting me before I was paid in December, it didn't go off, now I'm trying to get them to redebit me, phone just rings at all departments. Kindly get retentions to contact me. Had no issue with the device or service, just scary that I can't get through on any emails or calls. I would like to cancel my contract with you'll.
