Spree - Bad online shopping

24 November 2017, I placed 4 orders totalling to R 2800 on Spree and paid for them same time and there after I received an email confirming that my payment was received and will receive my orders before the 6th of December. On the 28th of November I receive an email to my 2 orders are ready be shipped and then on the 29th I receive an email to say that they are out of stock they have credited my account. I was so upset has I had been given false information all along and I phoned Spree and was assured that my remaining 2 orders are packed and all the items are there and will be shipped soon I even requested that I have this on email and it was confirmed on email and this morning I get another email saying they are out of stock and have credited my account. This kind of services is unacceptable, for me this is false advertising because if they didn't have stock then they shouldn't advertise that they have and I would have bought from other shops that were having a sale on that day and to say your account has been credited is not good enough because no where else will I get any Items on sale now!!!!!!!!!!!!
