Pathetic service

I ordered a Queen Bed Set in December.The bed set was delivered to me but the base was a queen size and the matress an extra length. I immediately called to log a complaint. I stayed with the bed for about 2 weeks. I called several times following up on when the bed will be collected and replaced. Bed was collected after 14 days. Its been almost a month now my account still has not been credited and I havent got a replacement for the bed.The mistake was on their side but am the one suffering and inconvenienced coz of your poor service. I have called several times following up and all your consultants do is tell different stories daily. Am the one running after you yet you delivered a poor service to me and are not even bothered to fix it. I am so dissapointed and very angry. I have tried to be patient with you guys but honestly am not happy with your return policy or procedure. You deliver wrong goods to me. I report the next day only for you to come and collect them after i call you 10 times following up. Collection was done and its been over 14 days still my account has not been credited again, i call you daily to do a follow up and all your customer service consultants tell me different stories daily. Am so frustrated and dissapointed about your service. When you want someone to order you call them daily but to solve a customer complaint the customer needs to be calling you and follow up. You dont even bother to call me. This is very inconveniencing. Pathetic service
