2 attemps at the branch and 3 online with no help

Good day, I initially visited your branch early Dec 2015 to change my mobile number linked to internet and mobile banking. I filled out forms and was told that I would be able to start using the service later that day.<br> I tried the service a few days later as needed to add a beneficiary but the OTP still went to the old number which is not in use. I complained on the FB page a few times and got the standard \we will contact you\" response which no one ever did. I do not have to visit your branch and expected my request to have been resolved the first time. I visited your branch again in Feb 2016 and was asked to fill another form and got the standard apologies and my OTP still goes to my old number and mobile banking does not work as it asks me to register and the fails stating that the account already exists presumably looking for the old number. My attempts at doing internet banking states that the OTP service has been disabled. Hugely inconvenient and the worst experience ever, I should know, I am a customer experience manager. How are you going to resolve this and compensate me for the inconvenience?."
