Worst customer service ever

Disgusted with the level of service at cell c Middelburg mall, brought 2 devices in on the 24th of January 2022 a A32 Samsung phone and my hauwei router, phone just didn't want to come on and router battery started swelling,I tried calling numerous times to find out what was the progress on the repair of the devices with no joy, today I decided to come in 16/02/2022 phoned wherever the devices where sent to repair the quote for phone R2500 and the router quote R1500 these repair amounts where not even explained when I left the devices in the store that's how use the personnel is in that store, because it's under a year old I thought it would be repaired under warranty, what a waste of time I could of just taken phone n bought a new router if this was explained to me, a brand new pocket router is R500 so how they get to R1500 I don't no but anyway I will never do business with cell c again I will wait until my contracts expire as I have 3 devices never to renew them again because of this dismil service or non existent service I received, good bye cell c for good.
