Bad internet banking services

My internet banking services was blocked almost 3months back due to a debit order that was unpaid. Called customers services to reactivate internet banking. Thay adviced me to go into the branch so thay can activate the services same day. So I did. It got activated that day and was working for one dag than blocked again.... Went back 4 times already same thing just work for one day then blocked again. Called customer services to activate it and say that i am willing to wait 3 working days if thay can just fix this problem. So 3 days past... Internet banking works (yay).... One day and off it goes again... It is a real nuisance as this is almost 3 months and going in the branch takes time ( thats way i got internet banking).
