Hi. For the last few weeks I have had trouble receiving texts. They usually arrive 24 hours later, almost to the minute. I can send texts. It doesn't matter whether I'm at home, work or outside. I have no trouble making or receiving calls, WhatsApp or anything else.
I spoke to the call centre but they just said that it was a problem, they were waiting for 'investment' and she waived my bill for the next month - nice but no help!
