POOR SWERVICE AND QUERIES NOT RESOLVED DESPITE SPEAKING TO A NUMER OF DIFFEREN CONSULTANTS

I have had endless problems in joining the bank. I app**** on line for a black card, and was told by the courier my platinum card was ready for delivery. I told them to keep this card as it was the wrong card. I phoned the bank on many occasions to to get this resolved,. They informed me to accept the card and then to upgrade. They assure me that they would get the courier to release the card. This never happened. Finaly after nearly 3 weeks I got the card. I did all the required steps and got DIamond status. I app**** for the black card . They system rejected it . I logged a number of calls only to find they had sent my wife 2 cards which only one was activated. The problem with the error was that I had to cancel the second card. This also took a number of calls to find the answer. FInaly i get upgraded to find my pick and Pay rewards hav ereduced fronm 75% to 45 %. I start the process again to find why. The reason given 2 weeks ago was tha tthey only used my spend on my Black card which was received towards the end of October, The bank conformed tha ti spent adequate amount to get the 75%. I logged calls, references 8333 and reference with Jaques, ref ***, reference with Amo 8538 . I phoned to day and waited for a further 20 min to tell me that there has been no progress. Is this the way you treat new customers??????????? I now have also seen that they have not given me my full fuel reward from Discovery vitality. I presume that they have only taken into account my expenditure on the black card and not for the full month. I get different answers from different consultants on questions related to limit for different rewards. The training of your staff is very poor. PLEASE GET THIS URGENTLY RESOLVED.MY PATIENCE HAS RUN OUT AND I AM EXTREMELY FRUSTRATED
