SA Credit Assessors Harassments

In November of 2020, I was contacted by a lead generator at SA Credit Assessors. I agreed that an agent may contact me the following day at 5pm as I was working online and couldn't take their call at the time. 20min later they called again, to which I told them that I had already requested a call the following day at 5pm. The following morning they called again and I strongly advised them that they should take me off their database because if they couldn't communicate efficiently, then I do not want to speak to them let alone do business with them. They continued to persistently call me every day sometimes up to 3 times a day after that. I blocked their number but they still called anyway. They leave messages which block up my inbox. So I called back and complained and asked them to officially take my number off their database and to STOP calling me. They STILL keep calling. On 28 January 2021 I wrote them an email to ask yet again for them to remove me from their database. I got a reply back to say that they have removed my number. BUT, guess what?! They have now upped their calls to 4 times per day!! I have received 37 calls from them since 28 January 2021 (today is 11 Feb)!!! This is now harassment and I will take up legal advice. If you see the number *** do not even answer their call because otherwise they do not leave you alone.
