Cant Upgrade to S8+ (pre-order)

<p>I have tried to order the S8+ since 11 April. I have done it online twice last week and no one called me or sms me or email me. I didn not receive an order no. And then received a mail today: </p> <p>Dear ANNA MARIE WALSH</p> <p>Thank you for your loyalty to Telkom over the years. Your contract is due for a renewal on ********** 575. Samsung has finally launched the S8! As a valued customer, if you upgrade to the Samsung Galaxy S8 or S8 Plus, you will not only get a wireless convertible charger but stand a chance to be one of the first customers to upgrade and get a LIMITED R10 000 MSC voucher towards the cruise of your choice*........I tried to upgrade through the link in the email. Nothing. Called Telkom numerous times. Eventually after an hour on hold, someone came on the line to tell me that they will only deliver the orders 22 May. Firstly: Does your online pre-order not work? secondly: Are they really only going out late May? Why Is it so hard to upgrade with Telkom? I have 2 contracts with them and had both for 4 years. Why am I now finding it so difficult to upgrade? Do I really have to move over to another network?</p>
