Shocking service

Its impossible to get someone to sort out a problem with the account. Last month, during the unrest the pharmacy requested us to obtain our meds from our local pharmacy as they could not deliver. We did so and paid for all our meds (mostly chronic) The very next day they delivered. I was contacted by Pharmacy Direct and they said I could submit proof of payment and they would reimburse me (over R2,000) and I could then in turn pay for the medication delivered. I emailed proof of payment and never received acknowledgement. I have spoken to 3 people saying they will look into it, but they never get back to me. I have left messages on their callcentre line option for them to phone me, as I cant sit for 10 mins each time on my cellphone waiting to speak to an agent. I now received an sms saying I must pay for the meds delivered. My emails to the person who contacted me in the first place, remains unanswered as well
