I have heard from some of our clients that they have been receiving automated and annoying nuisance calls from an oven cleaning company. I can confirm that it is not us. It is not something we would do and we are amazed that a company is having any success with such approach.
I have taken the text below from a reputable oven cleaning company's website and I think it is good advice:
Please be aware that ‘National Oven Cleaners’ who are making nuisance calls are not part of our company.
Please report them to I.C.O. at firstname.lastname@example.org or call them on 0303 123 1113
We do not cold call or make nuisance calls, please be assured of our continued high standard of service.
