I ordered what I thought was replacement stainless steel bars for my spirit 300. And discovered Weber only makes the enamel version for that model grill. After a discussion with customer service they quickly agreed to do exchange service for the correct enamek bars. For convenience i paid an extra 16gps for a door to door exchange service. And paid effectively twice ie once for the incorrect stainless bars and again for the enamel bars in the expectation i would be credited back the value of the stainless bars when they received them back. However, despite re packing the bars and signing for the delivery exchange riverside apparently did not receive the bars. And have yet to credit my account. Having paid for two sets of bars and a special return exchange service organised by riverside I am extremely disappointed there had been no further response to my mail. I bought my barbcue with extras and spares from Riverside in good faith. But this leaves a bad taste since courier is responsible. And it seems no action is taken.
