Sent wrong package

I purchased a bed from Groupon which was delivered right on time and was very happy that the service has improved but to my surprise the service is just getting worse and worse.<br> On Friday last week I received an email from Groupon telling me that my bed is on my way and I received the bed then later on I opened the parcel so that I can assembled it, so the package was two different boxes the bigger box with the flames of the bed was correct but the other box with the attaching pieces was for a different bed. So what type of service is this where I phoned Groupon and spoke to some guys there and sent them several emails and was promised that I'll get the feedback on Monday meaning today but up to now no email or phone call.<br> Maybe Groupon are rich now they don't need my money I'm so shocked that this is happening after experiencing the worst service couple of months ago, this time I thought there service has improved meanwhile it's just getting worse.
