Poor Service!

We were invoiced for October billing, made payment (same banks for both parties) and sent POP to the billing department's email address. Used invoice number provided by WebAfrica as our payment ref. on EFT. Payment would have cleared almost immediately, as banks are the same. Next day our account was suspended for non-payment, although paid the previous day - It seems their billing department does not check if payments have been received before suspending accounts?! Called and waited over 10 minutes on a the line before anyone assisted. WebAfrica needs to improve their billing processes & service.
