No Service whatsover

I received an sms that my account is blocked due to an arrears amount. I've been phoning, faxing and e-mailing for the past week now in order to get an explanation, but nobody at Pharmacy Direct is able to assist me. I'm non the wiser and left with a blocked account while my medical aid pays the account in full every month.<br> <br> Tired of this ridiculously inadequate service.
