Shoppers Drug Mart complaint: Refill request

I requested to fill out the prescription for Dexcom G6 sensors and transmitter on Dec 23rd, 2021 and I have been told that it will be ready after Christmas and I will be called when it is ready. I wasnt call so between Jan 2 and Jan 18th I went to Shoppers a few times to ask what s happening and every time they told me it will be ready the next day and they will call me, that did not happened. On Jan 18 I have been advised to ask other Pharmacies around Langley if they have Dexcom and Shoppers will transfer the prescription. I did this and I got Dexcom from Safeway pharmacy the next day. Why they did not tell me this from the beginning? I am legally blind and I need the sensor to check my blood glucose. If I would get the sensors on time in December it would be covered by Insurance. I was forced to pay full price and now I have to pay full price again because the deductible for 2022. So lack of respect and consideration for a blind old person, it is hard to believe!
