You are oversupplying me and I cannot find a way to change the delivery times/ volume. The product is five star, no doubt but unless I get feedback from you on this message,I will cancel my order completely.
Can you point out how I can do that?

I was recommended Optibac by a women’s health physiotherapist because I was having trouble with urine infections and other problems post menopause. I have only positive things to say about optibac, it works and I recommend anyone having problems to give it a try, it does help to relieve symptoms associated with menopause.

10/10 customer service

I have used different products from optibac before, but wanted to start on a everyday one, I had about a hundred questions, and didn’t know where to begin, I emailed and spoke to the most helpful lady Hannah Glithero. She went above and beyond to help me, answered all my questions no matter how silly some probably were, she is a credit to your team! ⭐️.

Dear Terry,

Thank you for taking the time to leave a review.

I’m very sorry to hear that your first order did not arrive in full. I can see that you spoke with Paula following your email on the 12th, and a complimentary replacement was arranged and sent to you. From your original email, we weren’t aware that you would be away the following week when the replacement was dispatched.

I will send you a separate email shortly to confirm the products and delivery details on your subscription, so we can ensure everything is correct moving forward.

Please don’t hesitate to get in touch if you need any further assistance.

Great service from Optibac. I ordered the Travel Biotics for an upcoming holiday abroad and got them on offer. Free delivery & they arrived within two days of me ordering!
I also purchased these last year for an all inclusive holiday to Cape Verde. Myself & my husband had no tummy issues at all so I purchased again for our next holiday.
