Wasted my time

I was looking for a particular solar connector and cable, so I telephone Brights Boston. After being on hold I spoke to an assistant who assured me that Brights had that type of cable and connector. I drove to Brights Boston the next day. Firstly the 'electrical query' queue system is not great: I was in a queue on the right of some shelves and people kept going up to the assistant on the left side of the shelves and asking their questions. Next the 2 assistants tripped the whole shop while plugging an appliance into the live mains... Eventually I got to ask my questions. The assistant had no knowledge of the plugs/connector but did try and ask another member of staff. Then he took me to the aisle and showed me what plugs they had: none of which were fit for purpose. Behind the assistant was rolls of solar cable, so I was hoping that meant that the staff would have some information about solar connectors. It would have save me time and frustration if the person I had spoken to on the telephone has just said that Brights does not have those items.
