Bad service at Dischem

I've had the worst attitude from a Celestine who answered the phone on behalf of the pharmacy. I had called in as usual to ask for a refill for pick-up of my husband's prescription and the said lady who didn't even introduce herself or her role in the pharmacy told me the rules have changed as they are too busy currently. When I asked whether I could use today as the notification of the 'new rule' could we still get the prescription. Then I asked how long in advance we should call again for the next refill as my husband is on chronic medication she sighed and said 'make it a day in advance but you can come collect tomorrow or wait in the queue'. My airtime ran out then I called again and the same lady answered then I asked her whether we can't possibly get the prescription today as it was finished to which she responded 'it's not urgent but come in 3hours maybe it will be filled....sighed then continued do you understand? ' I said to her she was being very rude and she said 'oh ok bye'.
