Useless Santander service over 2 hours on the long distance telephone

I have been a member of Santander bank for many years but now things are just getting out of hand I tried to transfer some money from London to South Africa and I got locked out because of their stupid system are then had to call because they don’t have emails anymore and spent over two hours on the phone trying to rectify it and doing security clearances then they told me that they had unlocked it and I could go ahead and try and do the transfer again guess what I got locked out again they are just so inefficient they don’t know what they doing they tell me they can’t phone me and The number that they’ve got is 027 instead of 0027 I told them to check with their own BT about this now why must I carry the cost of two hours plus of time on my telephone to London to query problems that they have caused and I have decided I am going to send the CEO an invoice when I get my Telkom bill it’s ridiculous how they treat you and the way they carry on and they make no effort and they have a really no care attitude and I’ve got this big attitude about Being ****med when they had your details for 20 years and nothing has changed something is wrong with Santander and there’s something wrong with the CEO he has no control and doesn’t know what’s going on they very clever they don’t want any emails they only want you to phone them at your expense and I don’t have that expense to waste on at Santander something needs to be done and somebody needs to discuss this with me
