Sleeping Masters

They are sleeping at work masters. I bought a Two-piece Bedroom suite from their online store and then decided I needed to exchange it for a bed . I visited my nearest store to find out if I can perhaps exchange it at their branch and they said they can't do it because they are not linked to the Online store. I then logged a call, someone phoned me and told me the difference I must pay in, they will deliver the bed and take the bedroom suite. I waited a week and someone phoned me to tell me that they must collect the bedroom suite, refund it and then they will add the money I paid in weeks ago for the upgrade. This doesn't make sense to me , but anyway we did it like that and I waited for 2weeks before I logged a call to ask what is happening.I asked for a refund I provided all the documents needed for the refund I then thought now I will get my money back and go elsewhere .Three days later someone else emails me to ask for those documents that I already sent and now I am still waiting for the money because they are sleeping
