Poor Service!

I app**** for a wireless fixed line and data contract 3 weeks ago at the Telkom branch at the Boulders Mall in Midrand. The landline worked however the Internet did not work. I took the router back to the store only to discover that the data plan was registered on someone else's name. This was corrected at the store, however when I tried it at home it did not work (password was incorrect). I took the router back to the store and demanded a new router which was tested at the store only to discover that the new router had the same issue with the password. A technician was sent home and the problem was sorted after discovering that the password issue was a factory fault. This worked for 2 days, thereafter both the landline and Internet stopped working. A technician was sent home and found that the account was registered on someone else's name. This was fixed, however the Internet is not working again! I find it so frustrating that we have to pay for a service that does not even work most of the time. I find the service provided by the Telkom branch at the Boulders Mall despicable!
