Unprofessional

I changed my banking details over the phone with herbalife a couple of weeks ago.. On the 14th of February I got a phone call from herbalife to confirm my banking details of which they were captured correctly, the lady that I spoke with said I should get my commission by the 15th of February of which I didn't. On the 17th I phoned and I was told a story and that the money will be in by the 20th. I phoned again on the 21st and I was told they will escalate, the most annoying thing is that nobody communicates with me, I have to keep calling because nobody cares. The call Centre people say it's "finance". I called again on the 23rd, 25th and 27th and I was told that "finance" says the commission was paid so I must query this with my bank and they will send me a proof of payment. I still haven't received even that proof of payment and its now the 2nd of March. I get my salary in my bank account and I receive lots of deposits into this account but suddenly Herbalife claims that something must be wrong with my bank?

I am thoroughly disappointed after 3 weeks of chasing after Herbalife, so unprofessional
