bad service

on the 29/08 i upgraded my contract to a laptop PX CCD : HP 15 Celeron Windows 11 ,however when i turn in on the laptop it is very very slow as if it is an old laptop .so i decided that i contact cellc on Monday on the 05/09 to lodge the query *** and the guy a spoke to he told me that i will receive a call on Tuesday so that they can come take the laptop nd change it .today it is the 07/09 i then decided that i called cellc cause no one called me to follow-up and the lady by the name of Prudence answered the call and i asked to give her my Id number and ill explain why im calling she insisted that i tell her wats my problem and after ill provide my id insisted to give her my id first cause i hate repeating myself and she then answered as if she doesn’t want to help me with a down voice and the very boring part it is when she said :eishhh" as if I’m irritating her ...what is customer service ..what is soft skills ??? now she then told me that she doesn’t see my case that is lodged until i can provide the ref which i did and the feedback i got from her it was the case is still loading and i asked what is ur turnaround time as CELLC she said 48hrs and i told her but i called on Monday and nothing was done -no phone call or nothing .so to cut the matter short i think my relationship between me and cellc have come to an end they must come take their laptop and router and will take my business elsewhere cause this was not the first time receiving bad service at cellc .Thank you .
