Netflorist sms database removal

I keep getting the annoying sms's from Netflorist. I have on multiple occasions asked them to remove me from the database as you cannot opt out even though it gives you the option to do so. I have phoned and e mailed, them all to no avail. This is most annoying and I will never use Netflorist again. I have communicated with a Bohang, a Linden (the team leader) and now Rathabile who said she will come back to me. Avoid this lot to save yourself future frustration.
