WAITING ON UPGRADE FOR 3 WEEKS

Two of my contract numbers have been due for upgrade since 1 December 2015. I went to the iStore in Somerset West to upgrade the handsets via them as I would like Apple Devices. I completed my form for an iPhone 5. went back the next day to change the handset to an iPhone 6. I was told 3-5 working days. The said time has passed, data was loaded onto the simcard but when I went to collect the phone, they had the wrong deivce processed. I then completed another set of forms once again for contract number ending on 402 as well as an additional set of forms for my other sim that is also due for upgrade (Therefore 2x iPhone 6's). Again was told 3-5 working days. Again received an sms from Telkom that said my subspriction was updated. Went to the iStore last night only to find out that the upgrade was not completed for the two cell numbers I indicated on the forms, but that my data simcard which is a third number was upgraded. Once again i had to leave the store with no upgrades and no solution. It has been 3 weeks but Telkom has managed to mess up from start till finish. I have been a loyal customer of Telkom Mobile with 4 contracts with them but I have been struggling for 3 weeks!!!!!!
