A & E Factory Service - Maytag/Whirlpool - 3099 28th st se RIP OFF - Does warranty mean ANYTHING??? grand rapids, Michigan

We bought a freezer on 11/21/11 for hunting season, we put Venison meat only in it and it sits in my garage.  We noticed in June 2012 that ice was forming on teh bottom, even after we cleaned it out, it happened again, so we called Maytag, we troubleshooted adn they determined that a tech could come out under warranty to fix this issue as our freezer has a 1 yr warranty.  All we had to do was show the tech that we have proof of purchase and it is in fact under warranty, which we did. The tech got here and checjked the reciept, all good, then 20 minutes later comes into my home and says I owe 208.89 because it was a maintenance issue nto a waranty issue and that he already did the work and I do have to pay, so after a few questions, we went ahead and gave him a check and decided to deal with the company direct.  teh tech NEVER came in prior to doing the work and told me that I would need to pay 208.89 because of the issue and he never told me that is was not under warranty.  After SEVERAL hours on teh phone between Maytag. A & E and being hung up on, put on hold for over 20 minutes, etc, etc I FINALLY was able to get someone to refund me 130.00 (not the whole thing) -  BUT I have to wait 14-21 days for the check to arrive. I think this is pure BS and I am STILL out 78.00 adn Maytag/Whirlopool says my unit is under warranty and they have no clue why the tech would have charged me.  Needless to say I am STILL dealing with this issue.
