VODACOM & SAMUNG A72

On Wednesday 18th August I upgrade my phone and contact, I decided to go with an A72, when I got home I transferred all old data to my new phone. Made my first call, I use the speakerphone (loudspeaker) as due to my ailments while I'm working I can not hold a phone between my ear and my shoulder also the internet on the phone is so slow, I might as well have dial-up. I have always use the loudspeaker. On the call I was told I sound like I'm in a tin box I kept cutting out whether it was on WhatsApp on my normal phone. On Friday I took it back to the store I upgrade with Meyerdal Alberton they said the phone was fine. As I left the store the manager called me it was verified by her while she was trying to talk that she could not hear me it sounded like I was in a tin box and the phone cal kept cutting in and out. She asked me to try over the weekend which I did. Unfortunately, I was taken back in on Monday, they booked it into the ADVANCED REPAIR CENTRE (SAMSUNG). Only to be told that there was nothing wrong with the phone. She then phone them and told them she has personally experienced it, so then they wipe the phone and reload all new software. the phone was finally returned on the following Monday. Repeat the above I still has the same problem!!!!!! I was advised to take it to Samsung Eastgate, which I did I drove all the way there only to be met with completed rudeness extremely loud music in the shop very reluctant to help and not willing to take any responsibility, so a VERY wasted trip the only advice was to get and new sim card!!!!!! So made my way back to Meyerdal which they kindly did for free. Then I took my phone home to try still there was a very big problem so the next day (9 September) went back to the shop then again book my phone on to the ADVANCED REPAIR CENTRE!!!!! Hoping 3rd time would be a charm was I sorely mistaken!!!!! They took off all software and reloaded it again and that's all they did!!! but yet I only got my phone back on the 13th of September. I now have to pay for a phone for the next two years that does not meet my needs!!!! I have like I have downgraded from my S8 Edge, as I cant use this phone in the way I NEED TO!!! I am utterly disgusted with this situation VODACOM AND SAMSUNG!!!!! As no one will except that I have a dud phone know excepts responsibility or is willing to help. I was also told may it's my 200MBPS uncapped that is the problem, but when I'm not at home, then what I am with Vodacom so your connect is terrible too, I am tired of hitting refresh so I can get on to the internet. This ordeal has cost me a small fortune as I have had to buy and replace screen protesters by PODs not that they work well either. So now I am between a rock and a hard place I have been with Vodacom for 25 years and have never received such appalling service. I am considering going to MTN!!!!! You keep sending me service surveys I answer 0 to all then get a call they sats they will escalate the matter still heard nothing and this was done twice, then only to be sent another survey asking if and how the matter was dealt with. GUESS WHAT IT WASN'T!!!!!!!!!!!!!!!! Zero again. If his matter is not dealt with I will post this on social media seems the only way to get anything done!! As my service provider, I expect you to sort this out. Please note Meyersdal shop has done everything in their power to help they have been great but Vodacom and Samsung itself terrible NO SERVICE NO HELP they just don't care!!
