Need email address

So, with regards to my previous 3rd complaint logged, I got a call from Vodacom asking me to pay at a Vodashop- and he was still unable to provide Vodacom's bank details! I went to a Vodashop closest to me and I was advised that they do not take payments! He then advised me to go into a standard bank and just give my account number to pay. I went to Standard bank and waited in a long queue (which I had no need to do, had Vodacom GAVE me the bank details that I required). The teller then asks if it's a capital I or L in front on the account number and I have no clue! I had asked the man at Vodashop and he told me it's a number and not an alphabet. More and more each day I see how inefficient Vodacom is! I eventually ended up paying with an I as I was not willing to stand in that long queue again! Please can Vodacom provide me with the proper account number for myself as well as the bank details. Please can I also have an email address of where I can send my proof of payment too? Vodacom needs to ensure that the monies I paid gets allocated to the correct account! Awaiting an urgent response.
