The Courier Guy - how treat loyal longstanding customers like ****

<p>After 5 years of using the The Courier Guy I have close my account. I have spent more than a month trying to integrate my website with their plugin. They don't return phone calls, Clive Mayo Head of IT doesn't return emails. Sent an email to the MD to get help, no response. I discovered bugs in their plugin written by Dawpro, incorrect installation instructions on the website. After chasing them for a month I discover that the plugin just doesn't work if you have a client who places an order on your website and the order contains more than one product. When I informed Clive Mayo that I am shutting down the account his attitude was just "Thats cool, go somewhere else." I am going somewhere else and I'm taking my money with me! <br />Don't waste your time with these clowns if you want efficiency or decent customer service!</p>
