Telkom breaks my screen and then drops Samung tab

I got a Samsung tablet in good faith on a contract with Telkom 9 months ago. The tablet was in mint condition, but within a few months, the battery needed replacing. No problem. On 27 August, I took it to Telkom at Menlyn, to have the old battery replaced. A couple of weeks later, I was informed that it was ready to be collected. The screen was broken , yet it was fine when handed in. Telkom said they would repair the screen. I waited, waited.. and waited.I do not have a laptop, so my Samsung doubles up as one, on a daily basis.it. It was most frustrating. . I phoned Telkom frequently, but the service was pathetic
