Terrible service!

What a pathetic business to deal with. Went into IStore Woodlands on Saturday the 7th of January 2023 to upgrade my daughter's phone. We phoned beforehand and was advised that can make an appointment for a certain time. When arriving at the store, we were told that the guy dealing with MTN contracts are busy and that he will assist as soon as possible - note this after making an appointment for a certain time. Well, we waited....and waited.....and waited. Eventually was assisted after waiting 5 hours just to advise that it was declined. No idea why though. I then thought let me try and do an on-line application. This was done on the 11th of January. No response or update received since then. I phoned the IStore call centre on Monday the 16th to follow up. Was told that they will get a consultant to phone me. Eventually got a call on the 17th. Application was dealt with and a declined response received the next day. They gave me a copy of the response from MTN and I noted that it was approved. I then asked the consultant what the issue is and was told that MTN do not allow the full credit amount and I need to trade in the old phone to allow for a discounted monthly payment. I agreed to this and asked the consultant to arrange accordingly. I was then told that they do not allow for trade ins via the online application process. So up to date no further action from them to assist. I phoned MTN yesterday and they did an application that was since approved. What a horrifying experience from an international company like IStore. I will not recommend them for anything.
