Unallocated payment to my business account

I made a payment via eft on the 3rd of September and to date after numerous calls to agents at Vodacom no one can locate this payment and allocate it to my business account. My account is not reflecting with correct payments and balances. Almost every week my line is suspended and I have to call in over and over, speaking to many vcontractor agents with no call back and promised escalations. I have many names and email addresses and to date no one has had the courtesy to contact me and address the allocation to my business account. I have emailed the proof of payment along with my bank statement which reflects the payment made accordingly but still no resolution. With line constantly being suspended this poses as a huge business service issue on my side and losing out on my business deals. Please may I be rewarded a call by someone in Vodacom who knows what they doing and can provide the service levels they should be giving their paying customers. Looking for an updated account and an urgent resolution to my payment made in September.
