Ordered oil online for collection at Reading branch. Got confirmation of collection order a short while later and drove to Reading (20 mile round journey) to collect. Despite on line confirmation, the assistant at Reading branch advised me that they hadn't stocked that oil for about 2 months so had none, despite the online confirmation saying it was in stock. Basically he said there was nothing he could do but relented after a while once I pointed out my wasted journey etc. He then found an acceptable alternative, which resolved the problem & so saved the day for me and GSF's reputation.
