Complain

Good day may someone please help me with Telkom with their rude agents I ordered a cellphone contract with them online which was suppose to be delivered to me on the 30 October 2018. Its only came to me on the 31 October 2018 yet again its took them 3 working days to activate my sim card after they activated my sim card I found out the device has a problem with the micro phone whenever I am calling someone they cant here me unless I am using ear phones I called them on Monday which was the 05 November 2018 the agent was rude she didn't help me with nothing instead she sent me to the branch I went to a nearest branch yesterday at Johannesburg CBD main street square which was Tuesday the 06 November 2018 they told me they going to replace my phone immediately only if I came on the 05 November 2018 because according to them the phone was delivered to me on the 30 October 2018 and they only do immediate replacement within 7 days from delivery after 7 days all the damages on the phone they are at my cost and. They advised its either I call the call center for assistance or I go to the nearest Huawei branch for repairs and they cant assist me cause when I took the deal online. What I am failing to understand the damages on the phone were not caused by me so I call the call center after holding for 30 min the agent refused to help me because he said I cant speak English fluently then he dropped the line I had to call again and I hold for another 30 minutes I requested to speak to the team leader her name is Charmaine she told me a lot of things to I didn't understand so I requested for cancelation of this contract cause I didn't understand what she was telling me she advised I must pay a fee of R800 I failed to understand why should I pay a fee for their device I cant even use or am I paying a fee of their bad services I cant handle
