Converting to alternative account to keep me as a customer what a joke

I have been trying to convert my account from a student achiever account to a mymo account as I was informed via SMS that I qualify for it and they will squash any debt I have in the account but I haven't had a single person from standard bank call me regarding this I had sms yes as it said the they want to keep me as a customer but I don't even want to be a customer with this bank anymore due to the fact that their service is terrible.
