Penny Talk reviews and complaints

I signed up for Penny Talk in May 2020. Until November, I was able to make calls to mobile phones in Papua New Guinea. (People do not have landlines there.) When message from Penny Talk is always, "I'm sorry, we cannot connect your call at this time." I can call these numbers using my mobile phone or regular landline service, so the problem is with Penny Talk. These two methods of calling are very expensive, though, which is why I signed up for Penny Talk. I called customer service twice. They promised to research the issue, and call me in 24 to 48 hours. They did not call back. Three days ago, April 7, I called customer service again. They made the same promise, but yet again have not called back after nearly 72 hours. The "ticket number" I was given is [protected]. Here's what's really creepy: Today I called every Penny Talk number I could find, but every one of them was dead on my line. That is, the calls would not even start. Then I tried calling using my mobile phone, which is not my account number. The call went through, but after I put in my account number [protected] and PIN and 0 for customer service, the line went dead. I could find no way to email or message Penny Talk, so here I am. They are charging me $1 per month to keep active a service I cannot use, and now apparently cut me off. If this is not resolved very soon, I will contact the credit card company associated with my account, stop the auto charge, and file a fraud complaint. Thank you.
