Very bad service from Telkom

I percussed a LTE 10 + 10 gigabyte contract from Telkom Bloemfontein College Square on the 17-02-2015 the sales person Lelorne Jcaobs said there is an error on the system I must come back the next day. I went back on Wednesday still this error was not resolved and she said I must come back on Thursday. On Thursday the error was still not resolved she said I must come back on Friday. On Friday she said the problem was she entered my ID number incorrectly and that is the reason for the error. Finally I was able to percuss my contract. When I arrived home I discovered I received a faulty device (LTE modem) I took it back the same day. The sales person Lelorne Jcaobs said it was the last one they had in stock, but they will have new stock on Monday 23-02-2015. I went back on Monday afternoon and there was still no stock on this item, then on Tuesday I went back and still no stock. Lelorne said she will call me with an answer on Wednesday but she didn't I went back today but she still didn't attend to my problem. This is the worsted service I have received from any company and would not recommend anyone to do business with Telkom.
