You are not entitled to call me, leave me alone!

Dear Woolworths,

Your customer service is dismal. I have a new cell number and the previous user of it probably owes you money or you are trying to sell me a credit card or something. Whatever the case, I'm not interested. I opt out! Leave my number alone, please!

Your call centre staff has no ability to fix the problem themselves or to escalate the call to a supervisor or manager and you don't answer the queries logged on your website.

What do you suggest I do next?

No, I don't mention the number. I shall mention it in a private response.
