Bamboo Matresses don't keep their promise

I could give them 0 rating if that would be possible. I'm utterly dissaponted by Bamboo matresses' service. I app**** for a refund on the 23rd of March and was told I will receive it within 7 days. Till this day I haven't received my refund. Or atleast any promising refund sms. This is completely unfair on my end. I have tried emailing the manager and everything to request when I will receive my refund but I still haven't received it. I'm completely upset and will never consider purchasing anything from Bamboo Matresses again!
