Just plain rude... Call Centre

Given an amount to reconnect services, amount paid services not connected. Phoned call centre but told I was given the incorrect amount and services will not b connected until full payment. No apology for previous inconvenience, was told supervisor will call me after 12-20 minutes but nothing. Was told they will listen to the call for confirmation but even if they can prove I was given the incorrect amount, there's nothing they will do. What ever happen do customer service and Client experience. What A Joke
