Spamming with - mails and sms's

Online orders.This has to stop. All this spam for each order. Last order had11 mails for one order, not counting all the Sms's !!. Now also extra mails from the store itself as well as the online platform. Your online team have also not responded to my e-mail complaint about this. !. I just want to order and know when to collect... thats it.
