Customer service is TERRIBLE

I'm a regular customer at this pharmacy because UNFORTUNATELY i cannot purchase my Libre sensors anywhere else.. I've had multiple problems (which i won't even get into) with this pharmacy but the last scenario has now been the tip of the iceberg!! I added on a additional item to my monthly chronic order, which i paid for there and then through the online purchase platform.. I approved the transaction on my banking app and the money was deducted. it's been almost 3 weeks and after speaking to MULTIPLE personel , I've yet to receive my product, nor have I received the refund which i've eventually asked for!

They cannot pick up my payment apparently and said I had not approved the online purchase on my banking App , yet the money deducted from my account...

Not to mention EVERY TIME I phone or message I speak to a different person and I have to REPEAT the WHOLE story EVERY TIME!! when speaking on the Whatsapp.. each response takes up to 30 min to an hour!!

VERY FRUSTRATED!! Your Customer Service is TERRIBLE!!
