I feel schemed

3 months back I got my whole house furniture from them to be delivered to my new place on the 1st of april,5 days b4 delivery they tell me the couch I wanted is no longer there,they gave me a substitute of the same colour damaged couch,I took it coz I ddnt have money to add on for another couch considering I was informed 5 days b4 delivery,I feel like they put me in a corner,I hate this couch with all my heart coz now it forces me to budget for another 1, 4 weeks back I exchanged my queen size mattress with xl queen sized,they told me the 1 I wanted is no longer in but they have something I can get immediately as Courior collects they will do an exchange,all I had to do was add on 2.5k,I did just that,took them 3 weeks to collect and now going on 5th week I still haven’t received the exchange,I called out of frustration yesterday only then I find out the 1 I paid for to get immediately is apparently damaged on its way to delivery and it was the only 1 left,they ddnt inform me and ignored all my emails and they are now expecting me to wait until the 17th of June to get a mattress,sleep in the ****py couch they gave me or I must add more money to get another available name,I asked for my money back,I must wait for 14 days send Id’s and more things that are more admin to me...If I want my old mattress back earlier I must go collect it myself at their collection point ..I feel schemed,disrespected and unfairly treated for someone that followed all their order.. I want the mattress I paid for as soon as today,I want the couch I paid for,I want an apology
