Invoice not received

I did not receive my invoice and statement on the 1st. I queried this by mail and received an automated response with ref number - RE: Invoice [#***]. no response until today. I send a follow up mail. no response until today. Yesterday I called and as always MTN is experiencing high call volumes (no wonder they have 11000 complaints on hellopeter...after waiting 20 min I dropped the call, I called again today and after 30 min finally someone accepted my call. The person I spoke to informed me that I can view my statement on line (thanks for that, but some of us need the original invoice to claim from our employers) he then promised me he will make sure his manager sends it to me. Aaah and finally a statement (note still no invoice in my inbox.. guess what the statement belongs to a Mr Xhoza. Thank you for sharing his personal information to a stranger. I will be make sure to give him a call and inform him that MTN is sharing his personal information to strangers. I have logged a claim on mtn's website and the automated response said I should allow for 5 days for feedback. Today is the 15th. I had to submit my claim to my employer on the 1st.. Maybe MTN should pay this claim??
