Call Centre raise my blood pressure

First I phone and ask them to phone back. 'On this number?' "yes please'. Nobody calls back. I phone again. Namosa tells me that they can't make calls. Medical aid rejected some R600 payment. I explained to someone yesterday that I am a pensioner and that I can only pay it from my Saasa grant early March. A few days ago I sent an email explaining butthat is ignored. Today I get an SMS demanding payment within 7 days. I hope that they have now recorded my offer properly. I have leukemia and my blood tests cost the medical aid over R20000 a year. I get top notch service from the staff at Flora but I am disappointed with your ineffient call centre. Don't they read emails? Sucks
