Shocking upgrade service

As a Cell C customer for almost 20 years now I had the most shocking service experience from the company. I upgraded two of my contracts 30 March 2021. One with a replacement phone A32 and the other one a Huawei P40. On 7 April I received one of the upgrades but a Huawei P40 lite. Called 8 April and Wender appologized and said making arrangements to collect the incorrect phone. 13 April when I called no arragements was made. Mellisa said after another apology that she will make arangements now. After 7 days when I called again no arrangements was done again. Poor Lerato was on the receiving end of a fuming customer but she arranged within 24 hours that Ram Coeriers collected the phone from me. But that is where it stopped again. Up to now I have not 1 upgrade succesfully delivered and for a month 6 different employees cant provide me with answers. The I turned to customer services. I have 3 case numbers *** dated14/04/21. Then *** dated 13 April 21 and *** dated 7 April 21. Al 3 said someone will call me within 48 hours. I am still waiting. Do I continue fighting a loosing bsttle Cell C or do I take my 3 contracts to one of the other suppliers and loosing my number which I am using for almost 20 years now.
