My Paydate is 25th

On Friday the 24th July, Telkom tried to collect their payment. I only got paid on Saturday morning. The is rather annoying as I have requested from Telkom to collect on the 25thand I did not receive any phone call nor a SMS to advise me that this will happen prior to the 24th. On Monday I received a SMS to say that I am liable for payment. Now, my problem is not that I had to pay. My problems are as follows... 1. If my numerous previous requests were adhered to to change the notification number from my wife's number to mine, I would have received an SMS to say that the payment would be collected on the 24th (my wife never tells me about the sms anymore as there has never been issues previously with collecting before the 25th) and secondly I am annoyed that I am sat with unpaid fees due to requests for collection are not being honoured. I am the client, I know what my payday is, I know that I get paid on a Saturday and I expect that should the 25th fall on a weekend that Telkom will then collect on the Monday instead of the Friday. I would MUCH appreciate it if someone can contact me via email with regards to this and also let me know how they (Telkom) will resolve my issue.
