Disappointed but customer service is improving
Follow up. 
Customer service rang me and we have a way forward for my bike although not an ideal situation.   I'm hoping my bike will arrive before my planned cycling holiday at the end of September and and email has been received to say I can expect it soon. However.. the fact remains I'll have a bike with a spec I didn't order but I've been assured this will be rectified once the parts are available. 
Disappointed with customer service so far. My build date delayed once (short email) which I can understand but my new build date was today (Fri Sep 3) Earlier in the week I rang Ribble for an update but got no information. Rang again yesterday and was basically fobbed off with ‘ the factory will send you a tracking number when it’s on its way to the store’. Then today I get an email to say delayed till 2022 because casettte not available. Suggestion I go for a smaller casettte but no number to ring back. What is a shame is that I wasn’t informed sooner. I booked a cycle holiday in Northern Ireland end of September hoping to use my new bike! Took out insurance…. Why leave the bad news so late?.. I’ve asked them to contact me on my mobile over the weekend.  We’ll see….
