Invading my privacy and personal life

Dear African Bank,

You try to call me many times in the last 2 weeks and then you had the audacity to call my office today and asked the switched board to speak to me just to do your silly sales call. First of all I find this DISRESPECTFUL and very UNPROFESSIONAL to call my office (which you never even had the number for and I don't know where you got my office number from because I just checked your data base with a sales consultant and you don't have it) to speak to me so that you can fish for my interest in either a loan or credit card etc. You guys are trespassing my privacy and there is no policy or right in place to give you the authority to fish my office number and then call me at my office to give me a sales call to make money. I am disgusted. Your sales people will not get through to me as every number of African Bank is blocked via True caller.
