iStore worse than ANC

Iphone is a good product but iStore is absolutely useless. I stay in a rural town 260km from the closest iStore in Woodlands Pretoria. I needed a battery replacement and tried to call the store to establish if they have stock and if they can assist me. This is not possible as the iStores do not have telephones, rather ironic. In the end I had to take a change and drive there. All went well, they actually had a battery and did the replacement. I picked the phone up at around 18:30 on Thursday 11 November and left for home the next morning after charging the battery to 100%. Not even halfway home the phone went dead. I tried charging it but it did not react to charging. My daughter assisted me in contacting the store via the customer help line. I received a call about an hour later and the person, Andreas, did his best to assist me but it seemed something serious was wrong with the phone. I asked him for his contact details and he gave me the e-mail address "***", once again confirming that they do not have a telephone line. This morning, Saturday the 13th, I sent e-mail requesting Andreas to call me back. The e-mail returned to me undelivered and with the message "Your message wasn't delivered to *** because the address couldn't be found, or is unable to receive mail". I then initiated a live chat with iStore and the consultant was Nonkululeko Mbokazi. I explained that the e-mail address was not working and requested her to arrange for the store to contact me at my office as I do not have a working cell phone. And here I have been sitting in my office on a Saturday waiting for hours for a call back from the Cellphone giant who can't even afford an inhouse telephone line for their stores. I rate iStore lower than than ANC and do hope that by some grace of God that they go out of business.
