No worries, I do understand. I will if you like refer your request to the admin in order to process a refund. But before I do that, please consider this...
I would like to mention that all of us experts here are doing this as a means of making an extra income, and in many cases like myself, rely entirely on this for all our income. On all questions we try to assist do our best to assist you, our customers, and in the end hope to make the customer, you, happy and that you will accept the support offered which in turn allows the system to put the money that you offered for an answer into the experts account. Not all the money however, a small portion of it. The other funds are given to the company for providing this medium for us to work together. It is a service driven environment. When an expert spends several minutes and often hours working with a customer going back and forth trying to assist a customer only to have the customer come back saying never mind, or I change my mind it is frustrating to the expert as well. And sadly sometimes customers get the answer that fixes the issue, but they say it was not fixed in order to avoid paying for the answer. Not that this is the case with you as I believe that AT&T is doing or have already done the repairs to the lines which fixed your issue.
I just wanted to point out the above so that you understand where the expert was coming from, and as to why we get flustered when in the end we get nothing for the work we did. This does not give any expert the right to be rude or condescending in any way however. So on behalf of all of us here I am sorry if what the expert said upset you.
So if you want to accept the support that was offered please do so, but if you would like a refund I will be happy to do as I said. Just please reply and let me know your thoughts. And as always, I thank you for your business, and any I hope to assist you in the future.
