Just couldn't be bothered in possible clients!

Been a client through my husband's work 5 years ago, when he was retrenched the policy was cancelled. A few months later when he found other employment we wanted to join again and sent mails, called and always got the response that someone would call back which they never did so we joined Bonitas with my employer. Now I've changed employers and cancelled Bonitas and want to go back to Discovery, yet same irritating problem. 1-2 weeks ago a call centre agent called me and filled in all our particulars and even said we won't have a waiting period and commencement date will be 1st May . He was to call back the very next day to confirm bank account number and just never bothered calling back for it. I was once again reminded why I went elsewhere. My husband is telling me to just go back to Bonitas as it doesn't look like Discovery is interested.
