Bidvest bank mandates

I was sent a link to complete a mandate in order to receive funds sent from UK . I have competed the mandate on two separate occasions and clearly it states that it only has to be done once in a calender year. I log on to the link sent via sms and I cannot edit my date of birth which resulted in not completing the document. Do these idiots not have their own data base in place this absolutely disgusts a person to think that you are requested to complete a document when you do not have to and how the matter cannot be resolved with as little *** as possible . Are these idiots professionals because tgey dont deal with such matters in the manner they should now they give a person the ****ing run about. Its disgusting
