Poorest customer service

I would like to send a review for a very bad experience by Bawas 145 church street PMB, We had done a layby for items for 6to 7 months. according to my understanding layby is to keep an item away for a customer for a certain period right and I also believe that we cannot layby items that are not in store? So we did that and as per their policy they do not refund which is not a problem cos we wanted the items. Now my problem is that we have been paying for stock that has been continued and we found out when we needed a collection mind you this is not the first time we did a collection and there were no goods so today the stock is discontinued so now they telling us that they can't refund because their policy that means we must now choose items we not interested in just so we don't forfiet our money. My question is Who is at fault here? Is it even allowed? What does consumer act says in thus regards? I suspect these items were sold cos when u layby something you keep it aside so in this case I doubt procedure was followed. Yes it was discontinued but you cannot lay away items that are discontinued so it obviously got discontinued while we were busy paying for this. I would really like to hear from the owner as to what policy is this? Does it comply with consumer act ?.This is unprofessional and unacceptable.. Extremely disappointed
