Very Disappointed with Store level Experience and Customer care Feedback

Extremely disappointing service from the Local store in Phoenix, and not much positive to add to in regards to the Customer care in regards to rectifying the said issue. After making a telecom order & collect purchase on 29/11/2020 and having firstly the order partially wrongly prepared as we ordered 2 x Med & 2 x small & instead all small was made. The order was supposedly rectified and when we got home the initial 2 x small was already colder in temp than the 2 x Medium due to the delay in preparation, but more so as per our original order- 1 particular flavour was to be swopped out which didnt happen. After failing to get the branch to rectify the error that evening after make 6 registered calls, (I have it on itemized billing) and the store did not take calls assumedly due to closing times. I called the Customer Care and lodged a complaint on 30/11/2020 @ 8:30am with Sheldron with a reference CAS *** and we concluded that call around 8:46am Further communication was with Linda 03/12/2020 @ 13:45pm, then with Manana 08/12/2020 @ 14:21pm. I also received 2 calls : *11/12/2020 30 sec-consultant asked if I was contacted and as I was not was going to follow up with the store again; *28/12/2020 30 sec-consultant asked if I was contacted and as I was not was going to follow up with the store again I received a further miscall 06/01/2021 10:32am (1 sec), and another miscal 07/01/2021 @ 12:54 *I called this morning 14/01/2021 @ 12:36 and spoke to Tandiweh and after 6min24sec got cut off Called back @ 12:44 and spoke to Gabby who assured me that some1 from management team will call me back as she confirmed all my details again. In this interim We have supported this same franchise over the days in between without prejudice yet still await a positive feedback.
