Error while making test payment

[akakJnr]

After I made payment on test mode, I get this error.

Exception - set_exception_handler(): Argument #1 ($callback) must be a valid callback or null, function "enrol_paystack_charge_exception_handler" not found or invalid function name

comment or replace ---- set_exception_handler('enrol_paystack_charge_exception_handler'); ----
with set_exception_handler(\enrol_paystack\util::get_exception_handler());

or create a new exception handler for the charge exceptions
