Fiendishly complicated to spend vouchers & poor choice

So, initially had to cough up £20 to extend my £80 voucher which I hadn't been able to spend during lockdown(s), which was annoying in itself. Then I decided to spend my £80 on Go Ape which was about the only thing on their site that appealed to us. However there was a very limited selection of Go Ape activities on the BAG website (e.g. adult and 1 child to do Treetop Adventure, 2 adults to do Treetop challenge etc) but not the activity I wanted (adult + 2 children to do Adventure+). I tried calling BAG customer service number but that's no longer available "to improve customer service"!? The chat function yielded a "computer says no" response from the BAG representative I spoke to. Then called Go Ape, who at least are still willing to speak with their customers, who suggested I obtain BAG vouchers for Go Ape sessions that could be converted to the actual activity that I wanted to do. More confusion ensued when my "voucher reference" was unacceptable to Go Ape and I had to obtain a 16 digit code from the BAG website. My £80 eventually ended up being worth only £60 so I had to pay Go Ape another £15 to get the activity I wanted. Never, ever, ever will I use Buyagift again!
