Disappointing service

I have newly registered by two children for high school grades. On the website, Impaq advertises to be "quick and easy" for registration. My nightmare of an experience has proven to be the exact opposite! The unnecessary complicated and 1001 step process is ridiculous!! Its 2022! Registration, necessary authorisations, debit orders and tracking of order should be done easily online. I finally got registration sorted - after much frustration-and now have to "just wait for the warehouse to email me to collect". The so- called tracking system doesn't tell you much and no expected time frame. I chose to collect as it would be 3 to 5 days. Gosh it took that many days just to sort out the frustrating registration and getting my payment allocated. Now we must wait even longer? Our school has already started and my kids cannot work without their books. I asked repeatedly for a way to contact the warehouse and I get told I must just wait. You cannot phone and speak to a human being. And don't even try the Impaq line, you get put on hold endlessly. What shockingly poor customer service - and I was told they have upgraded the system and so they have issues... or they have a high volume of queries... etc etc. Of course you have a high volume of queries!! Your process is inefficient and your service is poor!! Can someone please just get my order ready for collectio urgently. Thank you.
