Not recourse for the SMS message that my account won't be usable

I have recieved an sms stating that my banking services are to be stopped on the 21 September, so I callled customer services to resolve the issue and the person answered the phone and kept me on hold for 29 minutes. I am sitting here not knowing whats the status of my account. I am not sure if I should even let my salry be deposited in to this account
