Bad service

<p>Called in to querry an invoice. Was on hold for 48 minutes before someone answered. For a call center i think thats a total lack of customer service. They attended to my querry and when i asked how long before the querry would be sorted they told me I must call back in 24 hrs. I asked the person on the opoosite side, cant some one call me as i am not prepared to waste an hour on the phone each time i han a querry. He said no, I must call in to check. I then asked to speak to a supervisor or manager which he rep**** that all the managers / supervisors were not available. I find that hard to believe. </p>
