None delivery of monthly medication

Dear Sir / Madam

I am extremely disappointed with your service, a few month ago you incorrectly delivered my monthly medication twice. I sent an email and called you informing you of this (I waitied over 10mins on the call for someone to answer my call), wherein you indicated that it is fine you will not sent the next months medication. However the medication continued. Then suddenly you did not deliver 2 months medication. I called into the call centre and waited over 15minutes for someone to answer my call wherein you informed me that you will urgently delivery the medication. That was on the Monday, I then called again on the Wednesday as the script you put through was incorrect and you indicated you will reverse this and urgently delivery the medication by Friday. It is now 1 week later and I still have not received my medication. Over and above this I suffer from high blood pressure and I do not have any medications and I cant get it from a pharmacy as you have already claimed for the month hence medical aid does not allow two claims in one month. I tried the entire day yesterday to query this and waited over 30 mins for someone to answer my call to no avail. I even tried your customer centre manger Kiran and he did not answer. This is extremely poor service and can cause serious health issues.
