Very poor Service and even Poorer Manager and pension payroll

I receive monthly pension from Alexander Forbes This I received every month and suddenly got no payment in August First I did not get a payslip from infoslips, when queried this I was give two conflicting answers.Then suddenly I received a PDF copy from their administrator. On the payday I received no payment and again when I queried got conflicting answers and even a screen dump of "proof" that it was indeed paid.Checked with my bank and again NO evidence of any payment done by Alexander Forbes. Seniors staff suddenly do not take calls or return emails.I was given names to call at the payroll but again no person is available. Only the pensioner consultant is able to assist and all he gets is the same as what I get.Now I have to pay additional bank fees for NO fault of mine. Why is it that a group of professionals are unable to resolve a simple matter but hide behind what I see as "created" documents to shut me up until they fix up their own mess up.This is NOT acceptable when senior payroll personnel suddenly cannot take your call and use and excuse that they do not take calls or answer emails... Make one think they just do not care and should NOT be managers as it is manager that must step in to resolve issues that his staff has NO answers for.
