Discovery Bank Very Poor Service !!

I'm beyond words Disappointed !! Been banking with Discovery for a few years, I received 2x ***** cases opened on my account due to my business email being unaccessible for a few days where I could not communicate on time with my clients which I stated. Immediately I responded and attended the complaints once complaints were filled, both clients received their goods immediately and still my account is locked after I provided written emails from clients and their Banks departments stating they both are happy. I phone Discovery ***** Department a few times to speak to the person who is dealing with my cases and still after 3 weeks, they told me the agent who is dealing with my cases will phone me and yet no one phoned me to assist me with this matter? No one phone call? Both clients who filed the cases from FNB Bank and ABSA Bank both confirmed via email & phone that both cases were closed at their Departments and clients are happy - Still Discovery keeps my account locked with no communication from them. FNB and Absa bank were both supportive and providing friendly / excellent service to me everytime I spoke to them and yet Discovery provides no service nor support at all. NO SERVICE ! NO SUPPORT ! NO RESPONSE ! Is this how Discovery treat their clients? Looks like FNB and ABSA bank treat people who don't even bank with them with neutral respect and providing 5 star service. People, be aware before you bank with Discovery, this experience will give you an idea on how Discovery treat their clients.
