I recieved a coupon for an oil change special at monroe muffler and we went to the monroe muffler in Altoona, Pa. and we were told that they would not change our oil for at least 3 to 4 days. I called an hour later and asked for an oil change and was told to bring it right in. when I explained I had a coupon for 10.00 off they told me they couldnt get to it for a week. They next morning I asked my sister to call and ask for an oil change appointment, she was told she did;nt need an appointment, she was asked if she had a coupon and she stated "NO" she was told it could be done right now. My sister went with me immed. to the monroe shop and when they saw it was me with a coupon, we were told they gave the appointment away. (within 25 minuted of the call)Botom line, If you have a coupon at Monroe, Throw it Away, They will not even honor it.
