Payments not processed without OTP sent to cell from Standard

Previously never had issues purchasing from TakeALot even when they changed the payment so the customers bank, in my case Standard would forward a Verification Code to your cell. However, this morning after two attempts - nothing. Then tried logging onto my Standard Bank Online Profile & was unsuccessful because I did not receive my OTP on my cell. Tried Twice. Also no notice on the website regarding any problems. There are so many issues with Standard & they prove over & over again that the customer is of no importance & there Don't Care Attitude is astounding.
