Poor service

my account was overdue by an amount of 1258 on the 26th of November 1000 was debited off my account, upon calling the call center i was told that collections can only debit a certain amount which was a 1000 this is a lie as previously my account was debited of an amount of 1658 so clearly there has been a mistake some where. This is really fustrating as i now need to go and make a payment why should i do this when there was ample money in my account on the first place. This is a total dissapointment and i have lost all faith in Telkom Sa. What is even more dissapointing is that i had asked for a Manager to call me back and that was never done this is just appalling customer service. If this is how telkom operates im ashamed to be a client of this company that just doesnt bother about their valued customers. Im utterly dissapointed especially that my line is suspended and nothing is been done. Instead of focusing on huge advertising get your customer right. I really think its unfair that i as a customer should suffer be cos somebody debited the wrong amount and since no response was given clearly there is an admission of guilt here
