Medlife — Phone call reassurance

After making a written complaint to medlife on the 11th August of supply of medicines supplied of excess charges i was promised a refund of rs500. Its past a week no refund has been made nor a call to say abt the delay. Being a senoir citizen if feel false promises were made just to pacify me. Kindly look into the matter and inform me about the delay. MRS T GONSALVES
