tired of poor service and mistakes

went into Telkom store on 26/03, asked to change account from private capacity to business capacity, stood in line for one person, got given a form and filled it in. Then stood in another line and was told the form I was given was incorrect so had to fill in another one. It took them 2 hours to process my change over. I was told to pay R700 deposit which I did in store. A few days later I received an sms saying I still owe then the R700. I called the 10217 number which is the business line. I hold for 30 minutes, lady tells me she will try help me but she's from residential. I said I called the business line and got through to you. she says they are short staffed so maybe diverted their lines. What she can see on the system is that instead of them changing my details, they actually created a new account so now instead of changed details I have two accounts. And guess what she cant help me change it, I have to deal with the Manager at the store I went to who also doesn't answer her phone - Pamela
