Poor Service

I have been with Stanlib Beneficiary care for 17 years now...I am the guardian of my daughter...the problem started maybe six months ago...The service was from excellent to worse service ever, I am not happy at all they don't reply to emails if you make phone you will hold on till you run out of airtime...My main concern now they pay the monthly allowance on the 1st of each month or even before the 1st but this Month I haven't received anything...send them emails and call still no reply
