Bad service to a loyal customer

So, upgraded on 30.04.2019. Nothing was said about stock shortages or delayed delivery. I upgraded two contracts at once. After SEVERAL calls to 084145 and 084143 where you hold in EXCESS of 60 minutes I kept being told both upgrade phones are in the warehouse awaiting courier collect. Today after 5 working days and being less than 6kms from their head office in Beclue, I only received one phone. I give up....... How does this work? If you had stock problems, tell me that from the start. But stop just giving standard answers. Was also told they will deliver on 8 May, national holiday???
