Builders service is way below par

We ordered a 900mm Black Slate postform top from builders 15 September 2024 and understood that it might take sometime to get it. With all the follow-ups made to Builders, updates was given and promises where made. Today 06 November 2024 all of a sudden they notify us they cannot supply this item anymore this after all the communication and promises the past 7 weeks. Now the interesting part will be, will it also take them 7 weeks to get our refund sorted. Seems like all the feedback that was given by Builders to us where just blatant lies. Now we are sitting 7 weeks later and still not any closer to completing the unit this top was ordered for. Fortunately Chamberlains Centurion can assist us same day with the exact same product we waited for 7 weeks from Builders.
