Cheapest and worst ISP

2 months ago my partner got a new job with a new salary date, which meant that when Telkom's debit order went off we would have no funds available. We called Telkom and asked them to change the debit order date, the consultant told us it was done but didn't tell us it might take 1 month to be in effect. That was July, then at the end of July they tried to debit us on the wrong date, this meant WE had to pay a fee ( to telkom and our bank) for not having funds on debit order date. We called again at the beginning of August, the new Consultant said there were no changes made to the system and we had not changed our debit order date, so we changed it AGAIN. Then at the end of August, we were debited on the wrong date AGAIN. Then when we called back we were told that it takes a month to come into effect. Bear in mind we did see that our account was paid before statement date as soon as my partner was paid. Then on the 14 September 2018 we were debited R1500 (our contract is for R705 per month), then on the 15 September 2018 we were debited ANOTHER R1500. We then called in and were advised to go to our bank and stop one debit order as it would take a few days before the money would be reversed with telkom. We then did this and prior to doing this we were told the system reflected that we had paid and were not in arrears, however after we had the second debit order reversed our account showed we were in arrears. Which made no sense. We were trying to upgrade our Telkom contract as we work from home, however we cannot do that because our account is in arrears. We have been calling Telkom everyday since the 17th of this month, it is now the 21st and we were advised all 4 times we called that it would take 5 hours to refect in our account on their system. But every time we called it would take another 5 hours for it to be done. Then we called again today because we were told it would definitely reflect by last night at 9 pm. However this morning when we called we were told that the account does show that we paid but because we were in arrears we would have to wait 7 to 10 working days before our account on their system would update. Then we asked for a number in collections department so we could speak to someone, the consultant said she doesn't know the number. We then asked for an email address we could use, the consultant said she can't give it to us because she's not allowed and she doesn't know it. Honestly if Telkom wasn't the only LTE network offering the bundle sizes we need, we would find another ISP, however we can't because everyone offering a line in our area goes through Telkom. Honestly telkoms service is so ****py, it actually makes me consider moving to an area with an independent ISP, just so I don't have to deal with this. Not to mention the fact that before their mess up I had not missed one payment, now it has affected my partner's credit score because it shows we have missed 2 consecutive payments. Honestly it would be a miracle to get a reply on this especially since we have logged a query that was immediately closed the next day without so much as contacting us. To make matters worse our speeds have been at their lowest (less then 1MB) and somehow we are still at fault for getting almost non existent service. Our internet is so slow, even WhatsApp can't receive messages at times.
