SHOCKING customer service and fancy web portal that malfunctions

For two years we've had finance with Wesbank as flawless customers. Last month a ***** tried to ***** funds from the account in some **** and so on their debit order date, the funds weren't available. I immediately tried to log in to customer service on the website. No luck. So I emailed them. No response. I've emailed them four times in the last few weeks - they have not bothered to respond and in the meantime a debit order has gone off. Today I get a message that we've been "handed over". There is nowhere on their website to lay a complaint and the only email address available is a black hole. Unless you want to spend hours on hold - this company wouldn't know customer service if it smacked them in the eye. I have their payment - but since they wont reply to me with deposit details I cant get it to them - so they're *****ing up my credit record and incurring costs I WILL NOT PAY - simply because their "customer service" is so shocking.

We've been paying an additional fee for 2 years for a service that does nothing - but I cant even cancel that because their email system is a black hole. I'm shocked that such a large company is so deficient in customer service.
