Pathetic After-Sales Service!

On 1st June 2015 I booked my SonyXperia Z3 in for repairs for a faulty earphone Jack.<br> My phone was with Telkom for a month and it returned still having a faulty earphone Jack & my battery life was never the same. I took the phone back to Telkom (Gateway) a while after to report the faults of the phone & the manager by the name of Zodwa laughed it off saying I have to book the device in again which I didn't because they don't ever have loan phones on hand & I couldn't be without a cellphone due to business purposes. According to the document I received with the phone when it had returned, the earphone jack & a few other parts were replaced, including the rear adhesive panel. On 27th December, my phone fell into water & when I inspected the device water was seeping out through the rear panel which was changed. I booked the phone in on the 31st December & it is now the 23rd Feb & I have had no feedback from telkom. I called the repair centre on 18th Feb & the lady went to check but never returned to the phone. I'm extremely frustrated with the after-sales service especially since we have 2 cellphones, 1LTE & 4 laptops contracts with them. All of which are for business.
