Poor customer service

Poor customer service. I requested in February for my loan debit order date to be amended, but nothing was done. In April, I ended up paying twice because of their failure to update the date. I sent numerous emails and received no response. I eventually managed to get hold of them through the app, but I still was not assisted properly. All I keep getting are excuses and false promises. To make matters worse, I have now received a notification saying my query has been resolved, when in fact nothing has been resolved at all. This level of service is extremely frustrating and unacceptable.
