Poor service

I've never dealt with a company like this making my life a living hell can't even upgrade my contract because I'm in arrears with Finchoice while they debited my account and it shows I owe them nothing, the call centre is a nightmare consultants just cut your call after waiting for half an hour to go through, they give different stories seems like they don't know what they're doing, you send emails no one responds you contact them via messenger still no assistance. This company is really giving me a headache I want my account to be updated ASAP. I don't want to hear that the system will update itself because that is absolute nonsense.
