I have a problem with my account and has been written emails since the 5th October 2022 this problem is still not solved I paid money in advance for medicine that was short delivered because of a problem with an outstanding amount on the account NOW this was not my fault since I always pay the co-pay according to the invoices I received so after 2 months their account department realize the mistake and send me a SMS to pay this amount outstanding which was a rather bid amount and as pensioner I work very careful on my budget it was hard to be able to pay such a sum at once I had no idee about what the problem was and queried this I have send several emails with copies of the original invoice and the prize on them this went on since October eventually I received an email where the account department did journal entries to correct their mistake Then I had to make a loan to pay the amount at once. On the 25th of November I was informed that it is too late to send this claim to my medical aid then handed over to someone else again the old story from pillar to post. My account is in credit with the amount for the medicine that was short delivered. I demand my medicine because I need it. THIS WHOLE PROBLEM WAS NOT MY FAULT I am a pensioner and are so stressed out about all of this. To phone them is an absolute nightmare. Since this problem was totally their mistake, they now need to sort it out with my medical aid
