Treating the customer UNFAIRLY

I received an sms confirming a quotation I dont know about. I called and advised that its ***** as I have not ordered a phone and was told it was with dispatch and they will stop it. I'm still getting sms confirming the order and today I'm being told to go to an internet cafe to scan a letter with 3 signatures. You have to have a better escalation process stopping a ********** activity at this early stage should not have to expose me to costs of an internet cafe and Covid
