Very poor service from Telkom

I currently have a contract with Telkom for two 8ta internet ****les and decided I wanted to upgrade to the LTE wifi router. The nearest Telkom store to me is at Wonderpark shopping center. When I went there yesterday I received very poor service! First off the queue was extremely long because there was only one teller open to help the public while two other Telkom employees sat in one corner talking to each other very loudly. After waiting almost 30 minutes one of the Telkom employees who was sitting decided to finally stand up and open another teller. When I finally got to the counter I was told that there are no LTE wifi routers in stock. I was also told that they get maybe one or two routers in per month! I was supp**** with a number that would enable me to upgrade me over the phone and then deliver the router to my house but unfortunately it was the wrong number! I then tried calling all the shops in Pretoria including Brooklyn mall, Hatfield, Kolonade, Menlyn etc. and the ones that actually answered the phones all told me the same thing... they don't have stock and they have absolutely no idea when they will get new stock! This is truly unacceptable and unprofessional.
