Bad service, not efficient, terrible staff and very unprofessional store

I am a first time user with Telkom and I think your service from your outlets suc****! I took a contract on the 28th of Dec 2017. I took a P10 lite and P8 lite 2017. The P10 lite had a speaker fault, booked the phone back in with the Westwood branch in Westville Durban and they advised the service centre only opens today the 8th of January 2018. Called the store- they first **** to me that there is no feedback as yet AND it was sent to the service centre. I managed to get the number for the service centre which is ********** and they advised the phone hadnt been recieved as yet. Called the store back only to find out apparently the courier services hadnt collected any packages as yet and apparently told by Cassandra that the service centre opened on the 3rd of January 2018. To top it off i recieved my bill for January this morning and i have to pay for a device which i never even started using as yet. I think Telkom employs staff that are not efficient, who are ***** and who cant even talk properly, I was told by the lady the first time- Shannon/Sharon "sorry mam you are mumbling on the phone and i am unable to hear you". Had i known this is the bad service telkom provides i would have never taken a contract with you guys. And to top it off lol i returned the phone on the 3rd day of its warranty. I think this is ridiculous. I am very sad and upset with myself for taking a contract with Telkom! I then called back now at 2.43pm and spoke to the man that assisted in booking my phone in - Dumisani and he did nothing to assist besides speak while I spoke and shout on top of his voice. He also confirmed the service centre opened on the 3rd of January 2018 and then after 2 seconds said oh no the 8th of January 2018. My phone is still sitting in the westwood store and has not been picked up by anyone or sent to the service centre. Was also promised a call by the manager of the store but to be honest I am so fedup. Is there any way of cancelling a contract? I am done and I feel shocked to know that Telkom who is such a big name and brand hires inadequate staff and managers to "let us customers down". Does anyone really care about customer service? Does anyone actually understand efficiency and actually doing their job????? I dont think so!!!!
