Citations appearing as numeric values

Question

I am having problems setting up my bibliography. I am using Harvard citation style yet my citations are appearing as numbers as shown in the picture below:
If I remove the options super,comma,numbers of the natbib package, I get the desired output though this will result in the disappearance of the numbering labels of my references in the Bibliography which is something I do not like. Below is my MWE:

\documentclass[12pt,openany]{book}
\usepackage[ 
left=2.5cm,
right=2.5cm, 
top=3cm,
bottom=3cm,
headheight = 3\baselineskip,
headsep = 5mm,
a4paper
]{geometry}
\usepackage[table]{xcolor}
\usepackage{graphicx}
\newcommand\HRule{\noindent\rule{\linewidth}{1.5pt}}
\usepackage{background}
\backgroundsetup{contents={}}
\usepackage{fancyhdr}
\usepackage{hhline}
\pagestyle{fancy}
\usepackage[super,comma,numbers]{natbib}
\renewcommand{\bibnumfmt}[1]{\textsuperscript{#1}}
\setlength\bibindent{0pt}
\bibliographystyle{apalike2}
\usepackage{etoolbox}
\usepackage{hyperref}
\hypersetup{
    colorlinks=true,
    linkcolor=blue,
    citecolor=red,

    urlcolor=yellow,
}
\usepackage{showframe}
\begin{document}
\chapter*{Acknowledgements}
I want this citation \cite{hapa:graphenum} to be \textcolor{red}{Harary and Palmer }\textcolor{black}{(\textcolor{red}{1973})}. I want this citation \cite{Knuth94:TheTeXbook} to be \textcolor{red}{Knuth }\textcolor{black}{(\textcolor{red}{1994})}.This text is quoted from \cite{datta2017latex} should be (\textcolor{red}{Datta\textcolor{black}{,} 2017}).
