Appalling service, no communication, unprofessional

This is my customer experience with you guys. Appalling service received. On the 19th Feb I log onto your website and apply for a loan. I then get an error message stating that my account already exists, I then select login, forgot password and proceeded to enter my email which then advises that my account does not exist, confusion?????? On 20th Feb, I call and they advise that it needs to be logged to back office to activate my account and update my email, I get a confirmation email with reference number WO:*** confirming my request. Today, 6 days later I call into the contact centre after waiting 7 minutes I speak to someone who is completely irritated and when I call her out on it she drops the line on me, very professional guys!! Nice! I then call in again, after 9mins I speak to a lovely day called Abigail, handle my situation and gave me great service. She advised that she will send a follow up and log a complaint. Now because back office do not work on weekends, I have to wait, again. This is worst customer experience I have ever had. I know you guys should be able to search calls using my cellphone number to track who I spoke to.
