How NOT to provide customer support

Example 1: Try contacting ICICI bank support over email through their website www.icicibank.com . They provide you an online form, where you can type in just 20-30 characters to explain your complex banking problem or a question about a particular transaction made. Once you fill in the data and hit submit, it asks you to come back after two days to submit form ‘again’ since its just been a day or two of the transaction happened.<sigh>. Alright. Come back and fill in the form again after two days and luckily i got response. Funny part comes now: email from a customer support comes in trying to explain the issue ( which I failed to understand) and at the bottom of the email its written ‘please do not reply to this email’.

Never thought that corporation of this big size do not understand how to provide support or probably they do not care.

Example 2: Call in AT&T Customer support. As always your wait time would be around 30-45 minutes. Call them towards the end of day and wait for your turn to get connected to agent. You will hear message meant something like ‘you are esteemed customer, please be in queue, someone be with you shortly’ wait for patiently as it might take 70-80 minutes. Suddenly they would prompt you that we should call back again as we have called the customer support after normal office hours<sigh>.

Why did they made me wait for 80 minutes on call then?
