Boycott Rawson Properties for SPAM calls

Rawson properties - I am naming and shaming Rawson properties for SPAM calls. On 20 April at 12:03 I declined a call and was immediately called again from 0213444806 - I answered and told the agent I did not want SPAM calls. He told me it was not a SPAM call and the consumer acts allows companies to call anybody. I told him I never gave permission to anyone to phone me and he continued insisting it was not SPAM. I am going to name & shame every company that insists on paying somebody to make SPAM calls.
