MTN not honest

Am disappointed with MTN they are ****s I took the R269.00 month to month WiFi agreed for the 4th debit order but they always debit late and charge me for late payments. I ended up going to pay in store and they debited still I requested a refund that it was later not given back and told me they can't see the instore payment. When I call customer care I get all types of stories why my services are suspended and wrote a couple of emails that never get a response for. Very poor service.
