Disgruntled customer

I have welcome tones that have caused noone to contact me. I use my phone for work and this could've resulted in a loss of business. I have Indian welcome tone I didn't accept or allow on my phone you cant get through to vodacom you cant remove the thing it's been on my phone for 4 months. I am English of course someone hears some Indian music they'll think they have the wrong number. Vodacom, sort this nonsense out! I am beyond livid. I get so many phone related spam calls and now this. Sort out your networ****
