Answer 1

You use href which does not submit the form. You need a submit button and change your action of your form to your view url. Try this:
{% block content %}
<form class="form-signin" action="{% url 'customer_view' %}" method="POST">
{% csrf_token %}
<div class="mb-3">
<input type="text" name="nam" id="nam" class="form-control-sm center-block" placeholder="Nam" autofocus>
</div>
</div>
<div class="mb-3">
<select class="custom-select center-block" name="mob" id="mob" >
<option>{{ customer.sponsor }}</option>
{% for i in sponsor %}
<option value="{{ i.mobile }}"> {{ i.mobile|add:' - '|add:i.name }} </option>
{% endfor %}
</select>
<div class="invalid-feedback">
Please select a valid Existing Customer.
</div>
</div>
<div class="mb-3">
<input type="submit" value="Search"/>
.

Answer 2

In your form, you write a button as:
Search
But this thus means that this is just a link that links to a new page. As a result, the browser will make an (empty) GET request to the given url, and never submit the form.
You can construct a button that submits the form with:
<form class="form-signin" action="{% url 'customer_view' %}" method="post">
<!-- … -->
<button type="submit" class="btn btn-primary btn-sm" role="button">Search</button>
<!-- … -->
</form>
That being said, a search is often done with a GET request, so you might want to change method="get", and obtain the parameters through request.GET.get(..) instead.
