Don't let customers suffer for you technical issues

I recharged with two amounts of R5 and R95 of which only R5 appeared ...when I called up to ask them of the R95 they told me to wait for 24 hrs as they are having issues with recharges from cellphone banking or apps....I waited that long to them be told to send a bank a statement which I sent twice...spoke to 3 different people who were supposed to open a case but did not only the 4th person opened it, I am not being told that the recharge was unsuccessful even though it reflects on the bank statement they asked me to send I then requested to speak to a manager n was left hanging on hold for 10 mins
