Poor customer service

I called customer service of Multichoice today to make arrangements for paying in advance yearly instead of monthly. I was polite and did not complain about anything at all, I only requested information about the procedure and I asked clarification about the dates of this arrangement. So, in my view, there was no reason for any adverse feelings. However, the accounts consultant was arrogant and patronising from the start. She sounded annoyed about everything I said and behaved as if she was doing me a favour answering my call, which seemed to have distracted her from some other important activity. She nearly ordered me to log onto the web site and update my telephone number which changed. One can see Multichoice has the monopoly on digital satellite broadcasting in this country, because if people had alternative choices, such attitude would not be tolerated. If competition had existed, maybe Multichoice would have taught their employees the benefits of showing some elementary courtesy.
