Standard bank service failed me

id like to write a review about standard bank, ive been with standard bank for the past 10 years and suddenly my account was blocked without my notification up until i called them yesterday and explained all the encounterments on the app, sometimes the app wouldnt allow to send money i would try to send small amount of money to my inter account and sometimes you do errors and put money like 0.55 cents or R1 or R5 to test if the app is able to send money to interaccounts or to someone else. when i closed my student achiever last year i was adviced that to have a good credit on my accounts either cheque or savings accounts my balances should have some money in so i have a question is it wrong for me as a student who gets money from siblings and im unemployed to move small money like R1-R5 or any amount thats less then R10 in my own accounts and thy begin to suspect *****? why didnt they send me an email or call me ? why did they have to wait and why are they keeping tabs up until a limit they just completely block my card to an extend to disowning me ? my question is why ? ive been a loyal customer for them and im very agrieved ... last night i spoke to more 3 service consultants and i was told to get a new card not these things of them anonymously closing my accounts if this is how you treat your customers, the least you would have done was to contact me and ask me about my accounts rather then being anonymous at first i thought i was being hacked but then no, thought there would be a better solution but to avail where they discontinued me because they said they suspected ***** in my account cause i would transfer small amount of money in my other inter accounts. so problem is when i went to the branch , i asked if it was large amounts of money being transferred to other accounts would they still block my accounts and say its ***** cause the way it was put it was like its someone else sending those small amounts while it was me the account holder trying to keep my accounts not to be on arrears whatsoever i got no answers all i was told is that they just following orders from head office from the ***** department and that im no longer a standard bank account holder . i requested to see my statement and then i was refused to see my statement , later on they show me my statement at the branch and when they interviewed me and then they transferred all my moneys and gave me a voucher and i got all my money back. but shame standard bank disappointed me
