10 Days to deliver 6km's away.

Upgraded my 2 contracts on 30/04/2019. Both upgraded to a phone and smar*****ch. Received one of the deliveries on 07/05/2019. Still waiting for the other. Made MANY calls to 084 ********** 43 and every other email and number I could find. Yesterday received a call from Cust care why I was unhappy with my email-cust-service. Told my whole story again. Was told, because I'm around the corner of your Headoffice would be better to go in. Went to Cellc HO. Sat for 40 minutes as only 2 consultants out of 10 desks assisted customers. Needed to come back to work. I also did 2 hellopeter reports before this one and the only reply I get is , "your query has been forwarded" …… Why do I get one upgrade and not the other?? Callcenter lady said on the system she could not find any fault or problem why my second delivery hasn't been delivered. This is now day 10. PLEASE assist.
