extremely rude!!!!

<p>Is this how you guys do business? </p> <p> </p> <p>Today (16/01/2017) at 14:33 I received a call from your call centre to offer me a package that will reduced my call rate and save me airtime. I am on a contract i do not use airtime, I receive a bundle that include free minutes and my data, when I indicated that the offer would have very little effect on my spend as I very seldom go over my bundle amount the agent stated: you clearly don’t understand English and slammed the phone down in my ear... i will never do business with your company!!!! Shocking!!!</p>
