Pathetic. Absolutely useless. Frustrated to the limit

I have a Paint Tech Auto Body Warranty with Regent. When I signed up, I received the email with contact details pasted below:

Dear Mr G Naidoo,

Please find correspondence attached regarding your Paint Tech Auto Body Warranty policy ***x. If you have any queries, or require any further information, kindly contact us on: Tel number: ********** Fax number: ********** E-mail: **********

I have just spent the last hour trying to change my account details since I switched banks. Call that 086 number, select the correct options (option 3, then 3 again, then hold for a consultant), listen to the entire disclosure, hold for a few mins then get cut off. Repeat the process again, get transferred to someone, confirm my details for security, only to be told "Please hold while I transfer you to another department" hold for a few mins more, the other department then picks up, confirms my whole life history for security reasons, then places me on hold while transferring me to someone else that does the same thing, the last person transferred me back to the initial point at the 1st stage where I have to press 3 then 3 again and then hold all over again. This process has been happening for the past hour. When I do get hold of someone, Im no longer going to change my banking details as I wanted to, im going to cancel the policy.
