Bad Service received from Vitality

I called Vitality in December. I had 3 queries. 1 was to receive the cash back into my bank account, the second was to determine how to prove that I used uber eats, nandos etc if i cancel my discovery card and the 3rd was to determine why I did not receive cash back for the shoe booster. Its been over a month and I had to call again to find out why my queries are not being answered. The consultant was only able to get back to me on number 1 and 3. I still did not receive any feedback on query 2 and when I spoke to the consultant after they called me for the otehr queries, she said she cant assist with no 2. This is SO BAD SERVICE FROM DISCOVERY.
